▼ The decay of Pd¹⁰⁹, Pd¹¹¹ [superscript g], and Pd¹¹¹ [superscript m] produced by thermal
neutron irradiation of
palladium targets has been investigated. Gamma
ray energies and relative intensities have been measured with a
high resolution Ge(Li) spectrometer. From energy sums and relative
intensity considerations level schemes for Ag ¹⁰⁹ and Ag¹¹¹ are
constructed. On the basis of beta and gamma selection rules, spin-parity
assignments are made for the levels of Ag ¹⁰⁹ and Ag¹¹¹
The results of this study are compared with recent theoretical
calculations.

▼ The organometallic chemistry of palladium(II) has slowly built momentum. While the early work focused on coordination of organic molecules to palladium, the evolution of industrial catalytic applications of palladium(II) compounds stimulated a search for reactions mediated by palladium. The growth is reflected in the appearance of several books I'2'^ devoted to the chemistry of palladium and about 30 reviews in the last 15 years. However, the complexities and subdeties of organopalladium chemistry have hampered the understanding and adoption of palladium mediated reactions in organic synthesis. For example, dramatic changes in chemoselectivity, regioselectivity and stereocontrol can frequendy be accomplished by minor modifications of experimental conditions, especially choice of ligands. These effects are mainly due to structural and/or kinetic requirements of Pd(II) intermediates involved in the specific reaction. To increase both predictability and apphcabiUty of palladium mediated reactions in organic synthesis, it is of great importance to investigate the structural and kinetic natures of Pd(Il) intermediates.

▼ Methoxycarbonylation belongs to the family of carbonylation reactions that are efficiently catalysed by homogeneous
palladium catalysts to give ester products. To date, achieving cost effect, stable and selective catalysts still remains a major challenge in ligand design and catalyst development. Reactions of 2-[1-(3,5-dimethylpyrazol-1-yl)ethyl]pyridine (L1) and 2-[1-(3,5-diphenylpyrazol-1-yl)ethyl]pyridine (L2) with the [Pd(COD)Cl2] or [Pd(COD)MeCl] produced novel
palladium(II) complexes [Pd(L1)ClMe] (C1), [Pd(L1)Cl2] (C2), [Pd(L2)ClMe] (C3), and [Pd(L2)Cl2] (C4) in low to satisfactory yields. The characterization of these compounds involved 1H- and 13C-NMR spectroscopy, infrared spectroscopy, elemental analysis (for compounds), mass spectrometry, and single crystal X-ray crystallography of compounds L2, C1, C2 and C4. The solid state structures of all the complexes were mononuclear and showed ligands L1 and L2 binding in bidentate coordination modes. Catalytic investigations of the
palladium(II) complexes C1-C4 indicated that all the complexes gave active catalysts in the methoxycarbonylation of olefins. Catalyst C2 containing two auxiliary coordinating chloride ligands and methyl substituents on the ligand structure was the most active in the methoxycarbonylation reaction. Reactions using HCl, an acid promoter produced the highest activity while p-TsOH gave no catalytic activity. Furthermore, changing the phosphine used from non-chelating to chelating resulted in decreased catalytic activities. Changes in catalyst concentration, temperature, pressure, solvent, time and substrate also influenced the regioselectivity and catalytic activities.

▼ M.Sc.
The main objective of this study was to identify and optimise the homogeneous catalytic systems for Pd(II) catalysed alkene acetoxylation in acetic acid to directly yield allyl or vinyl acetates as opposed to the usual aldehydes or ketones. Part of the intention of this study was to investigate potentially suitable re-oxidants and reaction conditions suitable for industrial application. The synthesis of butenyl acetate (via 1-butene acetoxylation) in particular is regarded as a potential value-adding opportunity for solvents producers. For safety considerations the study was performed with liquid alkenes (cyclohexene, cyclopentene, cycloheptene, cyclooctene and 1-hexene). Cyclohexene was used for the bulk of these studies. One of the most important and pioneering reactions in this field is the similar system for the oxidation of alkenes to ketones (the Wacker process). The related reaction, oxidative acetoxylation, is the result of the discovery of the Wacker process. The problems associated with both these reactions is the difficulty in re-oxidising the catalyst Pd once it has been reduced in the catalytic process from Pd(II) to Pd(0). Various reaction systems have been developed to improve these processes. Some of the systems that have been developed in the acetoxylation of alkenes were investigated. From the studies it has become obvious that for ease of Pd(0) re-oxidation a co-catalyst, benzoquinone, is essential for the catalytic process. This system employing a co-catalyst required another oxygen efficient re-oxidant to oxidize hydroquinone once reduced from benzoquinone in the oxidation of Pd(0). The re-oxidant would in turn be oxidized by oxygen. Various types of re-oxidants such as Cu(II) salts, heteropolyacids and metal macrocycles (e.g. Schiff base complexes and phthalocyanine metal complexes) were investigated in the multi-step electron transfer process. The most promising of the systems was the Pd(OAc)2/ benzoquinone/ heteropolyacid (H5PMo10V2O40 .34H2O)/ O2 system. From the studies it was apparent that the type of the re-oxidant can influence the yield of the product. Various other parameters were found to influence the reaction outcome. The type of Pd(II) salt was found to be influential in the reaction, for instance Pd(OAc)2 was found to be a better catalyst than Pd(CF3CO2)2. The catalyst loading was found to improve the yield iv when increased whilst this was not trivial since Pd is expensive the system needed to have as low catalyst loading as possible. The type of alkene used dictated the rate of the reaction and the product distribution. It was found that the conditions used for cyclohexene were not transferable to other alkenes without changing certain parameters to suit the alkene in question. Cycloalkenes acetoxylation was found to proceed without the addition of the strong nucleophile additive NaOAc, whilst for 1-hexene acetoxylation the reaction did not proceed without the additive. The product distribution was found to also differ between cycloalkenes and 1-hexene. For cyclohexene…

▼ The adsorption and separation of Pd(II) from Pt(IV), Ir(IV) and Rh(III) by silica microparticles functionalized with triethylenetetramine (TETA), 2-(2-aminoethylthio)ethanamine (NSN) and 2-(2-(2-aminoethyl)ethylthio)ethanamine (NSSN) in 1 M hydrochloric acid medium was investigated by continuous column studies. The functionalized sorbent materials were characterized by microanalysis, SEM-EDS and FT-IR. Palladium selectivity of the sorbent materials was achieved by stripping of rhodium, iridium and platinum chlorido species with 0.5 M of NaClO4 in 1 M HCl while [PdCl4]2 was eluted with 3% w/v thiourea. The desorption efficiency of thiourea was confirmed by the SEM-EDS analysis of the materials after Pd(II) elution. Palladium loading capacity of the sorbents were in the order S-NSSN (23.85 mg/g) > S-NSN (12.70 mg/g) > S-TETA (4.97 mg/g). The extraction patterns on the sorbent materials were explained by considering the coordination chemistry of the ligand with [PdCl4]2ˉ and ionic interactions of [PtCl6]2ˉ and [IrCl5(H2O]ˉ. The square planar complexes, [Pd(HNSSNH)Cl2]Cl2 and [Pd(NSNH)Cl2][PdCl4]2, were isolated, analyzed by spectroscopy and single crystal X-ray, whereas evidence of the fraction of Pd(II)-TETA complex was obtained by HPLC studies. This provided proof of the inner sphere coordination mechanism as the mode of interaction of these ligands with [PdCl4]2ˉ. Trace amounts of Brˉ anions in ligands resulted in the inadvertent isolation of bromide coordinated Pd(II) NSN and NSSN complexes. The ion-pair salts of [TETAH4]4+ with [PtCl6]2ˉ, [IrCl6]3ˉ and [RhCl6]3ˉ were also isolated and characterized by microanalysis and IR to further explain the extraction patterns.

▼ In the pursuit of increasingly efficient and/or new
chemical transformations, homogeneous transition metal catalysts
are proving to be invaluable components of the synthetic chemist’s
toolbox. Notwithstanding the many important contributions made to
the area of synthetic chemistry utilizing other transition metal
catalysts,
palladium-catalyzed cross-coupling techniques have been
demonstrated to allow for a plethora of otherwise very difficult or
even impossible bond forming reactions to be realized. In this
context, appropriately designed ancillary ligands, which upon
binding to a metal center can influence metal-centred reactivity,
have played an essential role in the advancement of
palladium-catalyzed cross-coupling reactions. This thesis describes
a multi-faceted approach to the identification of effective ligands
for the
palladium-catalyzed construction of (sp2)carbon-nitrogen
and -oxygen bonds. A new series of P,O-DalPhos ligands were
developed and applied in the synthesis of of N-substituted indoles
via tandem
palladium-catalyzed cross-coupling/cyclizations of
ortho-alkynylhalo(hetero)arenes with primary amines. Notably, one
P,O-DalPhos variant, OTips-DalPhos, was demonstrated to offer the
broadest known substrate scope in this important class of
transformations, affording a variety of structurally diverse
indoles and related heterocyclic derivatives in high yields. Also
described herein is the identification of the previously reported
ligand BippyPhos as an extremely robust and versatile ligand in
both
palladium-catalyzed carbon-nitrogen and -oxygen cross-coupling
applications. Indeed, the use of a Pd/BippyPhos catalyst enabled
the cross-coupling of a range of (hetero)aryl (pseudo)halides with
primary and secondary amines, NH heterocycles, amides, ammonia and
hydrazine, with representative examples being accommodated in air.
The unprecedented scope of the Pd/BippyPhos catalyst in
carbon-nitrogen cross-coupling allowed for the development of two
novel one-pot, two-step syntheses of N¬-aryl heterocycles from
ammonia, ortho-alkynylhalo(hetero)arenes and (hetero)aryl halides
through tandem N-arylation/hydroamination reactions. A marked
selectivity profile was also observed for the Pd/BippyPhos catalyst
and successfully exploited in the chemoselective monoarylation of
substrates featuring two distinct and potentially reactive
NH-containing moieties. Finally, Pd/BippyPhos mixtures served as
robust and efficient catalysts for the hydroxylation of a range of
(hetero)aryl halides and ortho-alkynyl(halo)heteroarenes to form
phenols and phenol-derived heterocycles.

Proceeding from the favourable results obtained with achiral analogues, the palladium-catalysed 'metallo-ene' reactions of acyclic carbohydrate-derived 1,1-diacetoxy-2,7-diene and 1,1-diacetoxy-2-en-7-yne compounds proceeded in a stereospecific fashion to furnish chiral, multi-functionalised five-membered carbo- and heterocyclic products. A valuable consequence of the reactions of these geminal diacetate starting materials is that the products contain enolacetate, or latent aldehyde moieties. Further elaboration of these functionalities enables the facile entry to an array of substituted five-membered ring compounds, some of which have been identified as synthons or substructures of important natural products. In the presence of carbon monoxide (1 atm) the corresponding cyclic carboxylic acid products were obtained under mild 'metallo-ene' reaction conditions. Cyclised chloro componds were obtained by exposure of the 1,1-diacetoxy-2-en-7-yne substrates to Wacker-like conditions in the presence of an excess of LiC1. The highly atom economical Trost-type cycloisomerisation ensued when these enyne starting materials were stirred in acetic acid in the presence of a palladium(0) catalyst. The mechanism of the palladium-catalysed 'metallo-ene' transformations is discussed with respect to the enantioselectivity of carbopalladation of prochiral alkenes as well as the transition states. The topological influence of pre-existing centres over developing stereogenic centres is evaluated. Following indications that n-allylpalladium complexes can be prepared by the oxidative addition of Pd(0) to an a,13-unsaturated acetal, our next strategy was based on the use of suitably substituted A 2'3-pyranoside rings as chiral templates for the construction of multi-functionalised fivemembered ring systems via Pd-catalysed 'metallo-ene' cyclisations. Enantiomerically pure bi- and/or tricyclic products of carbonyl insertion were obtained in fair to good yields when these 'metallo-ene' reactions were conducted in the presence of CO under mild reaction conditions. Subsequently, bicyclic diene products were prepared via the palladium-catalysed cyclisation of Az3-C-glycoside derivatives. Important revelations concerning the relative stereochemistry of substrates for palladium-catalysed 'metallo-ene' cyclisation/carbonylation of unsaturated C-glycoside derivatives were made. The consecutive introduction of unsaturated C-alkyl side-chains at C-4 and C-1 of selected pseudoglycals via palladium-catalysed nucleophilic allylic substitution reactions accomplished the formation of chiral dienyne compounds. Palladium-catalysed cascade cycloisomerisation of these substrates effected the smooth synthesis of enantiopure tricyclic products. Cascade cyclisation of these highly unsaturated starting materials under Wacker-like conditions afforded…

▼ M.Sc.
The main objective of the research described in this dissertation, was the optimisation of the palladium catalysed hydroformylation of a-olefms. An evaluation of the efficiency of the palladium catalysed hydroformylation process required a comparison with the hydroformylation processes based on cobalt and rhodium. Variation of ligands (diphosphines of the size R2P(CH2)nPR2), solvents, acids, etc. had a dramatic effect on the products and the rate of the reaction. Trifluoroacetic acid was used to yield C-6 aldehydes from 1-pentene while trifluoromethanesulfonic acid yields C-11 ketones. Corresponding results were obtained with 1-octene as substrate. The length of the carbon bridge between the two phosphorous atoms has an optimum length of two in the case of alkylphosphine ligands, while an optimum length of three was found in the case of arylphosphine ligands. One disadvantage of the palladium catalysed hydroformylation reaction is that this reaction requires the use of bidentate phosphine ligands. These ligands are relatively expensive and also difficult to synthesise. The instability of the palladium complex and thus the precipitation of palladium were one of the major obstacles that had to be overcome. The use of additives not only increased the rate of hydroformylation but also increased catalyst stability, which in turn allowed an increase in the reaction temperature. This further increased the rate of the palladium catalysed hydroformylation reaction. These palladium catalysts were found to affect isomerisation of the a-olefin, but isomerisation was not a rate limiting process with respect to the hydroformylation reaction. Palladium catalysed isomerisation reactions occurred at a slower rate than the corresponding cobalt catalysed isomerisation process. However, with rhodium no isomerisation occurred. The comparison between cobalt, rhodium and palladium showed that rhodium is the best catalyst for the hydroformylation of a-olefins. The pressures and temperatures required for this process are much slower than that required for palladium and cobalt. The ligand used is triphenylphosphine, which is relatively inexpensive and non-toxic, in contrast with the more expensive ligands required for the cobalt and palladium hydroformylation processes. The use of palladium opens up the unique possibility of converting a-olefins into "dimeric" ketones, which show promise as precursors for the new class of geminidetergent

▼ The design and development of new chemical reactions is crucial to the ongoing success of organic synthesis research. In this work the scope and utility of a recently discovered regioselective
palladium-catalysed allylic alkylation (Pd-AA) cascade was explored through increasing the range of non-symmetric pyran-based biselectrophiles and β-dicarbonyl bis-nucleophiles that can be used in this reaction.
Four differentially protected tri-substituted dihydropyrans based on glucose were synthesised, including 2,3-unsaturated silyl glycosides and α,β-unsaturated lactones. These substrates were assessed as bis-electrophiles in the Pd-AA cascade. One silyl glycoside bis-electrophile, possessing a carbonate leaving group, was shown to be an excellent substrate for reaction with a number of cyclic bis-nucleophiles. Furthermore, a series of regioisomeric methylated 4-hydroxycoumarins were synthesised, tested and found to be equally effective as bis-nucleophiles in the Pd-AA cascade with both acyclic and cyclic bis-electrophiles.
Advances made during this research include a novel Ferrier reaction with silanol nucleophiles, which was found to produce silyl glycosides, albeit in low yields. Additionally, several Perlin aldehydes were generated by the Ferrier-type hydrolysis of 3,4,6-tri-O-acetyl-D-glucal and led to the discovery of discrepant structural assignments in the literature. Furthermore, a ¹³C NMR shielding template was generated as a tool for the stereochemical assignment of tri-substituted dihydropyrans.
An extended variant of the Pd-AA cascade was achieved by employment of the bisnucleophile Meldrum’s acid with the optimal tri-substituted bis-electrophile in the presence of H₂O. The reaction afforded a γ-butyrolactone that could serve as a potential intermediate en route to the synthesis of the biologically interesting compounds thromboxanes A₂ and B₂. This extended Pd-AA cascade, although currently unoptimised, is capable of performing five synthetic transformations in one-pot and holds the potential to improve on the current syntheses of the thromboxanes.

▼ Stereoselective alkylations are a very useful tool in synthetic chemistry and, specifically, natural product synthesis. One such reaction, named the Tsuji-Trost allylation, is a
palladium-catalyzed substitution with the overall transformation being the replacement of an allylic leaving group with a nucleophile. First observed in 1965 with the allylation of diethyl malonate [1], and in 1973 made asymmetric with the use of chiral phosphine ligands by B. M. Trost [2], the reaction has been studied and utilized extensively over the years. While there have been many examples of this reaction in the literature, few explore functionalizing the allylic electrophile. Functionalizing the "2" position of an allylic acetate or carbonate could prove to be a useful synthetic tool. Allylic acetates, chlorides and carbonates bearing a methoxymethyl group at this middle position were synthesized. beta-carbonyl ketones which work well under the Tsuji-Trost conditions were also synthesized. Phosphine ligands that provided enantiomeric excess with a variety of nucleophiles in allylic alkylations were used. Upon reaction with a
palladium (0) source, the pro-nucleophiles were successfully alkylated in a stereospecific manner. The work described herein investigates modification of the Tsuji-Trost allylation in which oxy-allylation is carried out with a high yield and high degree of enantioselectivity.

▼ Palladium catalysis has been utilized extensively in organic chemistry for the synthesis of complex molecules. Despite its abundant use and many successful applications, there remain challenging transformations, specifically with developing new chiral centers. The aim of this research was to explore the underdeveloped, weakly coordinating X-type ligands and their applicability in enantioselective reactions. The electrophilic catalyst, generated by the coordination of sulfonic or phosphoric acid ligands, was utilized to explore underfunctionalized starting materials, such as unactivated alkenes and aryl C-H bonds. Herein we report two Pd II-catalyzed enantioselective transformations: oxidative amination and 1,2-carboamination. The Wacker-type oxidative amination was accomplished with good yields and modest enantioselectivity in the synthesis of chiral indolines and a cyclic carbamate. Substantial loss in enantioselectivity was seen with ortho-substituted anilines. The 1,2-carboamination coupled a mild, directing group facilitated C-H activation on a series of aryl ureas with a subsequent chiral C-N bond formation. Electron-rich, para-substituted aryl ureas provided the highest consistent yields and enantioselectivities. Electron deficient substrates provided little reactivity and substitutions at the ortho- and meta-positions gave inconsistent results. To our knowledge these transformations mark the first enantioselective examples of Pd II-catalyzed oxidative transformations utilizing chiral sulfonic acid ligands.

catalytic applications of iron-based nanoparticles (NPs) in
Suzuki-Miyaura cross-coupling reactions.
Palladium “decorated”
[email protected] NPs (
[email protected]/Pd NPs) were prepared making use of
established reducing nature and coordinating ability of the
[email protected] NPs.
[email protected]/Pd NPs were evaluated and found to exhibit
high catalytic activity in a series of Suzuki-Miyaura
cross-coupling reactions in aqueous solution at room temperature in
air. The
[email protected]/Pd system was reused efficiently and only a
slight loss of activity was observed after the third reaction.
Furthermore,
[email protected]/Pd has special retention ability for Pd
species making leached Pd negligible. The effect of
[email protected] on the
catalytic activity for Suzuki coupling was investigated and no
visible effect was found. Three Fe-Pd nanostructures
-“nanodendrites” (ND), nanoparticles (NP1 and NP2) were synthesized
by simultaneous thermal decomposition of Fe(CO)5 and reduction of
Pd(acac)2. ND exhibit a dendritic structure with an average
diameter of 51.6 nm, while NP1 and NP2 exhibit a pseudospherical
morphology with average diameters of 12.8 nm and 17.7 nm,
respectively. The three nanostructures all contain crystalline FePd
alloy and iron oxides were formed due to exposure to air. They have
high catalytic activities toward Suzuki cross-coupling reactions,
and ND have the highest activity among them. ND were recycled by
applying a magnet and reused three times with some loss of activity
which is readily attributed to material handling
limitations.

▼ Disposal of chlorinated hydrocarbons is a major environmental concern
due to the lack of a satisfactory means of safe remediation at all contaminated
locations. Current technologies rely primarily on incineration, a process that
can lead to dangerous byproducts such as dioxin. If the chlorine substituent
can be removed prior to incineration, or other disposal method, the subsequent
steps of disposal pose less of an environmentally risk. The catalyst developed
in this study is designed to promote the dechlorination reaction.
A methodology for the production of a
palladium based metal support
catalyst is presented. This technique allows the
palladium catalyst to be
deposited on a copper metal surface. The catalyst is active in the
dechlorination of p-chlorophenol, which is used as model molecule
representing a range of chlorinated phenolic compounds. Hydrogen is used in
the concert with catalyst to affect the dechlorination. Chemical process rates of
0.3-1.0 cm³/g*s are observed.

▼ Palladium complexes bearing N-heterocyclic carbene (NHC) ligands, and their applications in catalysis have remained topical in the literature for the past two decades. Their versatility is due to a vast array of structural modifications possible that afford influences on metal complex geometry and reactivity, and alternative ligand binding modes. These have been extensively developed due to the wide range of catalytic applications for palladium NHC complexes and continue to remain of interest. This thesis describes investigations into several aspects of palladium NHC complexes with potential or known catalytic applications.
The synthesis of the novel bis(NHC) dipalladium(I) hydride complex `[μ-{(MesIm)2CH2}2Pd2H][PF6]` has been reported. (1H) `NMR` spectroscopic studies and preliminary single crystal X-ray and neutron diffraction studies on a THF solvate of this complex were indicative of possible solid state hydride dynamics. This hypothesis was probed by further variable temperature and low temperature single crystal neutron diffraction experiments, and by incoherent inelastic neutron scattering (IINS) experiments coupled with DFT-MD simulations. The simulations allowed us to approximate the rate of hydride transfer in the solid state. Laue single crystal neutron diffraction was also employed to examine the propylene-linked bis(NHC) complexes `[μ-{(MesIm)2(CH2)3}2Pd2H][PF6]` and `[μ-{(MesIm)2(CH2)3}{(PdH)(MesIm)2(CH2)3}2][PF6]2`.
The synthesis of chelated bis(NHC) palladium(II) dihalide complexes has been established to proceed via a pendant imidazolium mono(NHC) palladium(II) dihalide acetate intermediate. This intermediate was isolable for the `t`-`butyl` `N`-substituent and a series of complexes sharing the motif `[{(tBuIm)(tBuImH)CH2}PdX2CO2R]` were prepared with variations to the ancillary halide ligands and acetate substituent. The hydrogen bonding between the imidazolium C-2 proton and the acetate ligand was examined in solution by (1H) `NMR` spectroscopy and in the solid state by single crystal X-ray and Laue neutron diffraction. The `N`-mesityl pendant imidazolium mono(NHC) palladium(II) trihalide complexes of the motif `[{(MesIm)(MesImH)(CH2)n}PdX3]` were prepared and used to access the mono(NHC) palladium dihalide acetate intermediates of the form `[{(MesIm)(MesImH)(CH2)n}PdX2CO2R]`.
We expanded previous studies on chelated bis(NHC) palladium(II) complexes to include saturated NHC species through the preparation of complexes ([{(sMesIm)2CH2} PdBr2]) and ([{(SMesIm)2CH2}Pd(NCMe)2][PF6]2) and examined the catalytic activity of the latter towards ethylene and carbon monoxide copolymerisation, similar to studies undertaken on the unsaturated analogue. The reactivity towards formation of the dipalladium(I) hydride complex from the dicationic palladium(II) precursor under basic conditions was also examined.
Expansion of these saturated NHC complexes to include extended alkyl linkers was limited by the formation solely of the pendant imidazolinium…

▼ Biologically active compounds, such as molecules isolated from natural sources like plants and marine sponges, have long been of interest to the synthetic chemistry community. Synthetic routes towards these biologically interesting compounds are constantly being sought after and improved upon by synthetic chemists, because efficient synthetic routes yield not only the compound in question in mass quantitites, but also allow for the formation of a library of compounds bearing small changes in structure that are not found in the originally isolated compound. These small changes can potentially have dramatic effects on the biological activity of the compounds in question.
Nitrogen containing heterocycles appear in a wide variety of these aforementioned biologically active compounds, and for this reason have long been an attractive target to the synthetic community. Heterocyclic scaffolds such as substituted pyrrolidines are present in compounds that display a wide variety of biological activity, such as antifungal, antibiotic, and antitumor properties. Cyclic guanidines are also present in a large number of biologically interesting molecules, such as compounds that display antibiotic, immunosuppressive, and neurotoxic properties. While synthetic methodologies to access the scaffolds in question currently exist, the majority of them rely on preexisting substitution present in the substrate to afford the desired substituted products. This precludes the ability to rapidly synthesize a library of compounds with various substitution patterns that can then be assayed for changes in biological activity.
The research described in this dissertation details the development of a methodology to synthesize substituted, nitrogen containing heterocycles in a
palladium catalyzed, modular coupling reaction. Chapter 1 outlines the biological relevance of nitrogen containing heterocycles, and it details the previous efforts of the Wolfe group to synthesize the molecular scaffolds in question. Chapter 2 describes the synthesis of substituted pyrrolidines via a newly developed, anti-aminopalladation methodology. Substituted pyrrolidine products bearing previously unusable N-tosyl and N-trifluoroacetyl protecting groups were afforded in good yield. Chapters 3 and 4 detail the synthesis of substituted, cyclic guanidines from acyclic N-allyl guanidine substrates. Chapter 3 focuses on coupling said guanidine substrates with aryl halides/triflates, in which substrates bearing cleavable N-cyano and N-tosyl protecting groups were utilized. Finally, Chapter 4 describes the successful coupling of guanidine substrates bearing N-cyano and N-tosyl protectin groups with OBz-protected amine electrophiles in a variation on a 1,2-diamination reaction.

▼ A novel Pd(II)-catalysed C–H activation/aza-Wacker cascade sequence has been optimised for indoles bearing an N-tethered alkene and an N-acyl mesylamide group that serves dual purpose as a directing group and a C–N bond precursor. This optimisation was achieved by a combination of Design of Experiments and traditional reactant screening. The reaction is tolerant to functionalisation on the alkene and tether, as well as substitution at various positions around the indole ring. The methodology can also be applied to pyrrole systems. 24 successful examples of this Pd(II)-catalysed C–H activation methodology are described. A number of studies have been carried out in order to probe the mechanism of this cascade sequence. As a result of this an oxidative Heck/aza-Wacker mechanism beginning with amide deprotonation can be proposed. The application of this methodology to non-aromatic substrates, with a view to this being used as a potential key step towards the total synthesis of naturally occurring alkaloids and potential drug discovery scaffolds, was examined. The synthesis of the substrate necessary for the total synthesis of the alkaloid matrine was unsuccessful, so the Pd(II)-catalysed C–H activation of enamine test substrates were instead investigated. These substrates were found to be unsuitable for Pd(II)-catalysed C–H activation due to a lack of aromaticity and a lack of electron density. Proof of concept for the oxidative Heck/aza-Wacker cascade cyclisation of aniline-derived substrates is also described.

▼ The project was concerned with studying the capability of a micellar-enhanced ultrafiltration system (MEUF) to remove platinum group metal ions namely Pt (lV) and Pd (ll) chloro anions from aqueous industrial waste effluents. South Africa has the world’s largest reserves of platinum group metals (PGMs) and other valuable metals such as manganese, chrome ores, titanium minerals etc. which are required for new automotive and other technologies, including fuel cells, catalytic converters and lighter components. The consistent loss with the industrial waste stream and the toxicological effects of these precious metals led to the need to develop new and effective methods to recover them from industrial waste effluents. With such a wide variety of fields where these PGMs are used and the failure of the traditional techniques namely sedimentation, fermentation etc. to effectively reduce or recover these highly toxic and precious metal ions prior to discharging industrial waste effluents, it is necessary to explore other techniques such as membrane technology that can be used to recover these valuable species from industrial waste streams. The present study involved the use of a cationic surfactant, viz cetylpyridinium chloride, which was introduced into an aqueous solution containing
palladium and platinum metal anions. The surfactant forms charged micelles above a certain critical concentration value. The metal anions adsorb onto the available oppositely charged sites on the micelle surfaces and are then able to be retained by a suitable membrane. Hollow fibre ultrafiltration membranes with the MWCO of +/- 10 kD and +/-30nm pore size were used as a filter component in this study. For this MEUF system to be effective, it was vital that the anionic metal ion species adsorbed sufficiently onto the available oppositely charged sites of the micelles and that the micelles were retained efficiently by the membrane. Results obtained during the investigation made it possible to make certain predictions about the micellisation process. It was also found that, it was not only the metal ion: surfactant (M:S) ratio that was critical, but the presence of other electrolytes in the aqueous stream proved to have a huge impact on the capability of the MEUF system. Findings of this research study showed that the MEUF system using cetylpyridinium chloride (CPC) can be used to recover or retain Pt (lV) and Pd (ll) anions from industrial waste effluents. It was also found that PtCl6 2-, due to its greater adsorption capabilities onto the micelle surface than PdCl4 2- or PdCl3(H2O)-, was preferentially retained in neutral medium. This may be exploited as a possible means of separating the two metal ions. The developed system offers the following advantages over some traditional and current methods: simplified unit operation line flow process, smaller amounts of chemical usage and no solid toxic sludge to be disposed of. Applications of this work could be of vital importance in catalytic converter recycling, especially in Port Elizabeth where…

▼ This dissertation discusses the synthesis and reactivity of divalent
palladium complexes supported by diarylamido bis-phosphine pincer ligands (PNP). The PNP is a tridentate pincer type ligand which typically adopts meridional type coordination. The rigidity and tight coordination of the PNP ligand provides the unique opportunity to study the coordination of ligands such as O_(2) and C_(2)H_(4) to a single coordination site on
palladium, or the reactivity of a single empty coordination site trans to a weak trans-influencing ligand such as diarylamido.
Irradiation of [(^(F)PNP^(iPr))Pd-]_(2) under an atmosphere of dioxygen irreversibly produces a mixture of a monohapto
palladium(II) superoxide ((^(F)PNP^(iPr))PdO_(2)) and a
palladium µ-peroxide ([(^(F)PNP^(iPr))PdO-]_(2)). Under photolytic conditions these two complexes are in equilibrium with each other. (^(F)PNP^(iPr))PdO_(2), an open-shell paramagnetic species, was characterized by a combination of single-crystal X-ray crystallography, EPR, and ^(19)F NMR spectroscopies. In addition, irradiation of [(PNP)Pd-]_(2) under an atmosphere of C_(2)H_(4) produces a mixture of [(PNP)Pd-]_(2) and a ethylene-bridged dinuclear
palladium complex ([(PNP)Pd-CH_(2)-]_(2)). If the ethylene headspace is removed, and [(PNP)Pd-CH_(2)-]_(2) is irradiated it is completely converted to [(PNP)Pd-]_(2). This suggests that in the presence of ethylene these two complexes are in photolytic equilibrium with each other.
In addition, this dissertation will also discuss the synthesis and reactivity of [(PNPR)Pd]^(+) (R = ^(i)Pr, ^(t)Bu) cations. [(^(F)PNP^(iPr))Pd]^(+) cations are highly electrophilic complexes that are able to coordinate Lewis bases such as THF, H_(2)O, and even extremely poor Lewis bases such as toluene and benzene. In addition, irradiation of [(^(F)PNP^(iPr))Pd]^(+) cations in bromobenzene induces the abstraction of a bromine atom from bromobenzene, consistent with a metalloradical species. Addition of dioxygen to [(^(F)PNP^(iPr))Pd]^(+) cations generates a paramagnetic, cationic η^(1) superoxide.
In non-halogenated arene solvents [(^(F)PNP^(iPr))Pd]^(+) cations undergo a highly unusual photo-induced isomerization of the isopropyl groups on the supporting phosphines to n-propyl. This unprecedented isomerization is believed to occur via C-P bond cleavage and is driven by the decrease in sterics around the metal, which allows for the facilitated coordination of the arene solvent.

▼ In Pd/ceria catalysts, mixed Pd-Ce oxide formations at the cluster-support interface offer unique activity toward hydrocarbon activation. Both experimental and computational investigations in the literature suggest that unique Pd-O-Ce surface formations yield highly reactive sites on the catalyst surface. However, structural details and the corresponding reaction mechanisms governing the behavior of such sites are not well understood. As such, this dissertation employs Density Functional Theory (DFT) in tandem with classical ReaxFF modeling to determine the stability and activity of methane activation sites at the Pd/ceria interface.
The ReaxFF interaction potential is used to investigate cluster-support interactions at length and time scales inaccessible to quantum methods. In particular, this dissertation develops a hybrid grand canonical Monte Carlo/molecular dynamics (GC-MC/MD) approach that is suited to assess oxide formation in regions where the Pd cluster contacts the underlying ceria support. When coupled with DFT, this multi-scale approach demonstrates that Pd atoms incorporated in the fluorite lattice structure of ceria alternate between Pd4+ and Pd2+ oxidation states during operation. In general, Pd4+ states are effective hydrocarbon activation sites, as the dissociative adsorption of the hydrocarbon reduces Pd4+ to its thermodynamically preferred Pd2+ state. Therefore, maximizing the number of transient Pd4+ states under operating conditions is essential for achieving optimal catalytic performance. The multi-scale simulation methodology developed and applied in this dissertation can evaluate the trade-off between stability and activity exhibited by Pd/CeO2, and can be readily extended to other catalytic systems.

▼ The preparation of palladium carbene intermediates from diphenylketene is proposed. Experiments to trap these intermediates with alkenes have been conducted and optimized, with cyclopropanes being prepared in up to 69% yield. This methodology has shown to be compatible with olefins, ethers, esters, anhydrides and various benzannulated norbornyl derivatives. In addition, an unusual palladium(II) catalyzed cyclopropane isomerization has been observed. Various substrates have undergone this isomerization affording two different olefin products in up to 61% yield. A catalytic cycle for this process is proposed.

▼ This thesis describes the results of a study of inorganic and organometallic chemistry of palladium(II) with 2- and 2,6- disubstituted pyridine containing N-donor ligands. Ligands of this type have been used to assess the ability of palladium(II) to adopt coordination geometries higher than the characteristic square-planar geometry, to determine whether palladium(II) substrates will undergo metallation reactions with polydentate pyridine donor ligands, and to synthesise complexes in which palladium(II) is bound to carbon atoms of the ligands at sites other than those expected via cytlometallation reactions.
Inorganic complexes derived from the reaction of ligands, L, with palladium(II) acetate and chloride substrates have allowed the isolation of complexes of the form [L(n)PdX(2)] (where X= OAc, Cl; n = 1 (polydentate), n = 2 (unidentate)), [LPdX]X (L = planar tridentate; X=OAc, Cl), [L(2)Pd]X(2) (L = tris(pyridin-2-yl)methane; X = NO(3)), and the related poly(pyrazol-1-y1) complexes [(pz(3)CH)(2)Pd]X(2) (X = NO(3), BF(4,)), and [(pz(3)BH)(2)Pd]. X-Ray structural analyses show that, [(pz(3)BH)(2)Pd] and the cations L(2)Pd](2+) L = tris(pyridin-2-yl)methane, tris(pyrazol-1-y1)methane) have square planar coordination with two uncoordinated donor groups. An X-ray structural determination of the complex [LPd(OAc)](OAc) . 3H(2)O (where L = the 2,6-disubstituted pyridine ligand meso-(pyPhMeC) (2)C(5)H(3)N) has been obtained confirming the planar tridentate-, nature Of the ligand and presence of a unidentate acetate-group.
In conjunction with the investigation of the coordination preferences of palladium(II), the coordination properties of the new ligand. (pyPhMeC) (2)C(5)H(3)N, have also been assessed by the formation of methylmercury(II) nitrate complexes. Fractional crystallisation has allowed the separation of mesa and racemic forms of the complex, and further reaction with sodium cyanide has afforded the free ligand separated into its meso and racemic diastereoisomers. An X-ray structural study has shown that, the meso complex is four-coordinate and contains the ligand as a tripodal tridentate. Thus, the meso form of the ligand has been shown to exhibit two binding modes, planar-tridentate to palladium(II), and tripodal-tridentate to methylmercury(II).
Attempted cyclopalladation reactions of the ligands py(2)CH(2), py(n)Ph(3-n)CH (n = 1-3), and py(3)PhC, with palladium(II) acetate in glacial acetic acid has resulted in the isolation of a dinuclear (C,N1-cyclopalladated product of pyPh(2)CH; dinuclear chloro- and mononuclear acetylacetonato-complexes have also been prepared to assist with spectral characterisation. The remaining ligands studied form bidentate chelate complexes, [LPd(OAc) (2)], with no evidence of metallation products.
Similar reactions using meta-disubstituted benzenes, for example, (pyMeHC) (2)C(6)H(4), have resulted in metallation of the central benzene ring to give mononuclear (N,C,N)…

▼ M.Sc. (Chemistry)
Palladium-mediated carbon-earbon (and carbon-heteroatom) bond formation! is to an increasing extent playing a vital role in synthetic organic chemistry. The chemistry is usually performed under mild conditions, with the organopal1adium intermediates being formed in situ from inorganic palladium salts or complexes, and has good tolerance of functionality on the substrates. The palladium mediator may be present in the reaction in amounts ranging from stoichiometric to catalytic. Reactions requiring stoichiometric amounts of palladium may appear to be inherently uneconomical. Palladium, however, may be easily recovered in most cases, and may be converted into salts useful for catalysis, effectively offsetting the initial expense. 2 The use of polymer-bound palladium catalysts! has also been shown to be a viable method of palladium recovery. Palladium may form a- or 1r-eomplexes with organic compounds and, as with many other transition-metal complexes, a-palladium complexes are generally only stable in the presence of select ligands. Arylphosphines are most commonly used, and of these triphenylphosphine is the ligand of choice for its availability and low cost...

▼ M.Sc.
Several bis[1-ferrocenyl(ethyl)pyrazolyl palladium dichloro (complexes 1 and 3) and palladium chloromethyl complexes (complexes 2 and 4) have been synthesized by the reactions of 1- ferrocenyl(ethyl)-1N-pyrazole and 1-ferrocenyl(ethyl)-1N-(3,5-dimethyl)pyrazole with [PdCl2(NCMe)2] and [PdClMe(cod)] respectively. Furthermore, a library of phosphorus^nitrogen (P^N) ferrocenyl(ethyl)-amine and -pyrazolyl ligands have been successfully synthesized using the well known Ugi amine (compound 5) as intermediate. 1- [2-{diphenylphosphino}ferrocenyl](ethyl)amine and 1-[{2-diphenylphosphino}ferrocenyl](ethyl)- pyrazolyl Ni(II) and Pd(II) complexes were synthesized by reacting 1-[2- {diphenylphosphino}ferrocenyl](ethyl)dimethylamine, 1-[2-{diphenylphosphino}ferrocenyl](ethyl)- 1N-pyrazole and 1-[2-{diphenylphosphino}ferrocenyl](ethyl)-1N-(3,5-dimethyl)pyrazole with [NiCl2•6H2O] (compounds 12 and 16), [NiBr2(DME)] (compounds 13, 17 and 19), [PdCl2(NCMe)2] (compounds 10, 14, and 18) and [PdClMe(cod)] (compounds 11 and 15), respectively. 1-[2- {Diphenylphosphino}ferrocenyl(ethyl)-1N-(3,5-dimethyl)pyrazole (compound 9) was synthesized by two distinct methodologies. In one method, 1-ferrocenyl(ethyl)dimethylamine was converted to 1-[2- {diphenylphosphino}ferrocenyl](ethyl)dimethylamine before it was subsequently reacted with 3,5- dimethylpyrazole to produce 1-[2-{diphenylphosphino}ferrocenyl(ethyl)-1N-(3,5-dimethyl)pyrazole. In the other method, 1-ferrocenyl(ethyl)-1N-(3,5-dimethyl)pyrazole was converted to 1-[2- {diphenylphosphino}ferrocenyl](ethyl)-1N-(3,5-dimethyl)pyrazole before the reaction with 3,5- dimethylpyrazole, producing 1-[2-{diphenylphosphino}ferrocenyl(ethyl)-1N-(3,5-dimethyl)pyrazole. These compounds synthesized via different methods as well as their palladium dichloro complexes show different structures in solution, but solid state structural analysis agrees on the same structure. The structural difference in solution is contributed to the high degree of flexibility at the stereogenic centre of the complex. The Ni(II) ferrocenyl phosphine complexes 12, 13, 16, 17 and 19 exist in equilibrium between diamagnetic square planar form and paramagnetic tetrahedral form. The tetrahedral geometry is xvi favoured over the square planar geometry, purely on steric grounds, but the square planar geometry occurs with d8 complexes because of the more favourable electronic situation of the complex. Activation of these P^N palladium and nickel ferrocenyl- amine and -pyrazolyl pre-catalysts 10, 12, 13, 14, 16, 17, 18a and 19 with EtAlCl2 results in the oligomerization of ethylene to C4 and C6 alkenes, followed by subsequent Friedel-Crafts alkylation of the toluene solvent. Moderate catalytic activities of up to 659 kg of alkylated toluene products.mol-1 Ni. h-1 were observed for catalyst 13 at 20 bar ethylene pressure. In general, the Ni(II) pre-catalysts were more active than the Pd(II) precatalyst.

▼ Historically the majority of precious metal sols have been prepared in an aqueous medium, while a much smaller proportion have been prepared in various non‐aqueous solvents. Few however have been prepared in mixtures of the two, this paucity being the raison d’être of this study. The goal therefore was to perform a systematic investigation of the changes in the properties of rhodium and
palladium sols generated in mixtures of water and another organic cosolvent across a range of volumetric compositions. Six cosolvents were investigated: methanol, dimethylsulfoxide, acetonitrile, N,N‐dimethylformamide, acetone, and tetrahydrofuran. To stabilise the resulting sols against aggregation four protecting agents were used: poly(vinyl pyrrolidone), poly(vinyl alcohol), poly(acrylic acid), and arabinogalactan, which was a newly‐available polysaccharide extracted from the Western Larch tree. To reduce the metals from their precursor salts, sodium borohydride and hydrazine hydrate were used. The resulting colloids were analysed by Transmission Electron Microscopy (TEM), Photon Correlation Spectroscopy (PCS) and Ultraviolet/Visible Spectrophotometry. The size of the primary particles in the resulting sols was shown by TEM to be inversely proportional to the proportion of cosolvent in which they were generated. A theory was postulated to account for these changes based on temporary stabilisation of the metal nuclei by adsorption of cosolvent molecules. The characteristics of the aggregates observed in the TEM micrographs were shown to be independent of the cosolvent proportion, changing progressively but unpredictably across the composition ranges studied for most systems. This behaviour was believed to be caused by changes in the conformations of the protecting agents, which depended nonlinearly on the composition of the dispersion medium in which they were used. The measurements collected in‐situ by both PCS and UV/Vis were considered to be good indicators of the levels of aggregation observed in the sols ex‐situ by TEM, with any disparities between the two sets of measurements rationalised with relative ease. PCS measurements gave average hydrodynamic diameters of approximately 20 nm – 80 nm for sols generated in purely aqueous dispersion media, depending on the metal and protecting agent used. Infrared spectra were collected of carbon monoxide adsorbed to the surface of the particles of the sols in mixed‐media to determine the effect of the cosolvent proportion on ν(CO)ads. Sols generated for the aforementioned work were found to be of insufficient density for this purpose, so a series of high‐density sols were synthesised especially. Adsorbed CO was successfully detected on rhodium sols in mixtures of water and either MeOH, DMF, DMSO or MeCN. In these cases υ(CO)ads and its intensity decreased as the cosolvent proportion was increased. This behaviour was rationalised by competitive adsorption of the cosolvent molecules onto the surface of the colloidal particles, precluding the adsorption of CO molecules. The consequent…

▼ The research presented in this thesis describes the computational DFT study of homo and bimetallic Pd(n)Au(m) clusters of low nuclearities. Many studies on such species are already present in the literature but the originality of our approach rests on a detailed analysis of electronic structure. Thanks to these efforts, some answers and views have been brought to the many open questions that to day remain in this field.
The detailed electronic structure analysis has brought new features. The PdnAum clusters can be built step by step through simple concepts for chemists such as Lewis structures, resonance or hybridization. The Aum clusters have been described on basis of Au(2) dimeric units, which adjust themselves through donor-acceptor type interactions. This simplified model provides predictive information on the structural parameters as well as on the stability of these compounds. Introducing the back-bonding concept has highlighted the structural changes caused by the substitution of one Au atom by a Pd atom. The Pdn clusters, which are more difficult to describe due to the chemical inertness of Pd (saturated valence shell), have been built from sd1 hybrid orbitals, assuming overlap maximisation of the hybrids. Introduction of spin interactions brings an explanation to the increasing spin multiplicity observed for these clusters. Again, the most stable structures appear to be explained on the basis of smaller units (Pd(2), Pd(3)). The Pdn spin excess location was then used to predict the interaction with an Au atom, which bears an unpaired electron. Finally, all information collected after the study of pure completed by monosubstituted clusters has been used to understand the distribution of the various partners in mixed PdnAum clusters.
Resulting properties exhibit a logical and almost continuous evolution with the size and composition of the cluster. In this way, clusters with Pd-rich compositions adopt three-dimensional structures closed to Pdn clusters while Au-rich compositions favour pseudo-planar configurations. The choice of geometric descriptors showed that the PdcoreAushell structures correspond to the most stable situation as the uniform distribution or the segregation of the two metals are less favoured. Another interesting point is the fact that the mixed clusters are characterized by a gain in stability compared to their pure clusters counterparts. The evolution of stability as a function of the composition suggests a parabolic behaviour where the synergic effect is maximized for median compositions (n ≈ m).
In conclusion, although many issues remain in the broad area of metal clusters, this work lays down the foundation for future considerations. It has put forward an effective theoretical method guiding the analysis of such compounds and has shown the importance of a good understanding of the electronic structure in order to predict physico-chemical properties of these materials.

▼ Carbohydrates are an important source of renewable materials which can be converted into high added-value products. Sugar transformations should ideally be carried out with recyclable catalysts, in water, with the highest possible selectivity in the desired product. The aim of the present work was to explore the microstructural properties of the heterogeneous catalysts needed to carry out selectively lactose oxidation into lactobionic acid and lactose hydrogenation into lactitol. The first part consisted in the investigation of the influence of two functionalized supports (γ-Al2O3 and Cxerogel) modified by metallic precursor grafting and activation on the catalytic performances in lactose oxidation. The oxygenated functions were shown to be detrimental. This was confirmed by the results obtained with an inert support, boron nitride, which can be a promising alternative support, ensuring high selectivity. Subsequently, the optimal range of particle size within Pd/h-BN catalysts for high activity and selectivity was investigated and the optimal size was determined between 3 and 15 nm with no particles inferior to 3 nm. The effectiveness of Au/h-BN was also evaluated and it exhibited spectacular performances. Au/h-BN was shown to be a good candidate for thermal regeneration for recycling. Lactose hydrogenation was finally investigated with Pd/h-BN and particles inferior to 3 nm were also undesired. The selectivity obtained in lactose hydrogenation seems to be greatly dependent on the mechanism of each possible side reaction.

▼ In the constant race towards miniaturization, the scientific community faces multiple challenges regarding the characterization and control of the mechanical performance and reliability of devices and materials at the smallest scales. Thin films are materials presenting one extremely reduced dimension, from a few microns down to a few nanometres. The reduced dimension proved to be at the origin of new and improved properties of thin films as compared with their bulk counterpart, as for instance an increased mechanical strength. But, other properties deteriorate with size reduction like ductility. The objective of this PhD thesis was to study the deformation and relaxation mechanisms in nanocrystalline palladium films of various thicknesses (between 80 and 500 nm) in relationship with the microstructure. The ambition was to characterize, understand, predict, and, finally, to propose routes to improve the mechanical properties. An on-chip microtensile testing approach was used for this purpose allowing the measurement of the response under uniaxial tension with or without relaxation. Coupled transmission electron microscopy studies have been performed in- or ex-situ to unravel the underlying mechanisms dictating the mechanical properties. The yield stress, the strain hardening, the ductility and the strain rate sensitivity parameters of Pd films with various configurations and deposition conditions (thickness, twin density, dislocation density, confinement, ageing, annealing) have been measured and related to the elementary deformation mechanisms. A semi-analytical grain aggregate model has been proposed to provide a quantitative link between the microstructure and properties. Finally, the effect of hydrogen on the mechanical response of the films has been explored.

The main aim of the thesis was to optimise an optically interrogated palladium coated substrate to detect hydrogen at concentrations less than 1% in humid conditions (50-80%). An optical set up was constructed to investigate the change in the coatings in transmission at 650 nm on exposure to varying hydrogen concentrations in dry and wet conditions. Three different optical substrates; Polymer Optical Fibre (POF), Polymethyl methacrylate (PMMA) and glass were evaluated to determine the best support for palladium; criteria of selection were based on hydrogen detection performance in dry and humid condition (50%). PMMA was shown to be the ideal support as effect of humidity on hydrogen detection was minimal. Palladium was deposited by sputter coating technique and the coating thickness demonstrates a dependence on the deposition time and position of the substrate inside the coating chamber. The coating developed showed a response time of 1s at 5%H2, a detection range of 0-9.1% with a demonstrated detection limit of 200 parts per million (ppm) and a predicted limit of detection of 15 ppm. The rate of hydrogen detection was proposed to be diffusion limited for coating thickness up to the threshold thickness. At thicknesses less than the threshold thickness, the rate limiting step was related to the binding force between the coating and the support. The coating performance was unaffected by cross sensitive gases such as hydrogen sulphide, carbon monoxide, methane and ethene. In the presence of Relative Humidity (50-80%), the coating reached a limit of detection at 0.1% H2. However, over exposure to humidity lead to temperature effect which was compensated using a temperature compensation model developed. The surface of the coating developed was characterised by Atomic Force Microscopy (AFM), X-Ray Diffraction (XRD) and X-Ray Photoelectron Spectroscopy (XPS) and revealed that the coating developed is unaffected by the tests carried out through the PhD.
