1. Roberts, Lezah Wilette. Effect of Netropsin on One-electron Oxidation of DNA.

Degree: PhD, Chemistry and Biochemistry, 2005, Georgia Tech

One electron oxidation of DNA has been studied extensively over the years. When a charge is injected into a DNA duplex, it migrates through the DNA until it reaches a trap. Upon further reactions, damage occurs in this area and strand cleavage can occur. Many works have been performed to see what can affect this damage to DNA. Netropsin is a minor groove binder that can bind to tracts of four to five A:T base pairs. It has been used in the studies within to determine if it can protect DNA against oxidative damage, caused by one-electron oxidation, when it is bound within the minor groove of the DNA. By using a naphthacenedione derivative as a photosensitizer, several DNA duplexes containing netropsin binding sites as well as those without binding sites, were irradiated at 420 nm, analyzed, and visualized to determine its effect on oxidative damage. It has been determined netropsin creates a quenching sphere of an average of 5.8 * 108 Šwhether bound to the DNA or not. Herein we will show netropsin protects DNA against oxidative damage whether it is free in solutions or bound within the minor groove of a DNA duplex. Advisors/Committee Members: Gary B. Schuster (Committee Chair), Donald Doyle (Committee Member), Laren Tolbert (Committee Member), Nicholas V. Hud (Committee Member), Roger Wartell (Committee Member).

3. Remy, Matthew Sean. Group 10 Methyl Transfer Reactions toward Catalyst Development for Oxidative Oligomerization of Methane.

Degree: PhD, Chemistry, 2011, University of Michigan

Abstract Group 10 Methyl Transfer Reactions toward Catalyst Development for Oxidative Oligomerization of Methane by Matthew Sean Remy Chair: Melanie S. Sanford One of the challenges of developing a homogeneous catalyst for oxidative oligomerization of methane (OOM) is promoting a C–C coupling reaction from the product of alkane C–H activation. Heterolytic C–H activation of methane almost exclusively generates a monoalkyl-metal species. In order to make a new C–C bond, it is proposed that a polymethyl intermediate must be generated. Our studies showed that aryl disproportionation is far more favorable than methyl disproportionation. Careful tuning of ancillary ligands at monomethyl-palladium(II) complexes using density functional theory (DFT) calculations facilitated optimization of thermodynamics for methyl disproportionation. This allowed the first observed disproportionation reaction to form a dimethyl-palladium(II) complex. Heating dimethyl complex (tBu-bpy)PdII(CH3)2 (tBu-bpy = 4,4-ditertbutyl-2,2-bipyridine) to 100 °C produced a mixture of methane and ethane over 24 h. One-electron oxidants and 1,4-benzoquinone were found to be effective promoters of ethane formation from (tBu-bpy)PdII(CH3)2 at 25 °C. Mechanistic study of one-electron oxidation uncovered an oxidatively-induced methyl transfer reaction which produced ethane from [(tBu-bpy)PdIV(CH3)3(solvent)]+. Subsequently, one-electron oxidation of complexes of the general formula (tBu-bpy)PdII(CH3)X was developed as an effective method for generation of ethane from monomethyl-palladium(II) complexes. Platinum complexes, (N–N)PtII(CH3)2, similarly undergo one-electron to produce [(N–N)PtIV(CH3)3(solvent)]+. However, these platinum(IV) products are generally stable to reductive elimination of ethane. When the N–N ligand is designed to have steric interactions with axial ligands of platinum(IV), ethane reductive elimination becomes favorable, occurring cleanly over 8.5 hours in acetone and over 1 h in dichloromethane. This document describes experimental evidence for the generation of polymethyl palladium and platinum complexes from model palladium(II) and platinum(II) products of C–H activation subsequent ethane elimination from the polymethyl complexes. In an unrelated project, N-insertion into palladium-carbon bond was observed when palladium(II) complexes of bidentate C–N ligands were reacted with an iminoiodinane oxidant. The reaction was proposed to occur through an imido-palladium(IV) intermediate. Advisors/Committee Members: Sanford, Melaine S. (committee member), Banaszak Holl, Mark M. (committee member), Hollenberg, Paul F. (committee member), Lehnert, Nicolai (committee member).
