INVESTIGATIONS IN IRON, COPPER, AND PALLADIUM –CATALYZED C-H BOND FUNCTIONALIZATION
Transition metal-catalyzed functionalization of C-H bonds has been used as a powerful tool for the construction of C-C and C-heteroatom bonds. Within this dissertation, methods that allow functionalization of C-H bonds via iron and copper catalysis have been developed. Additionally, …

Radical additions of hydrocarbons, ethers and acetals to alkenes via allyl transfer reaction: A new chain reaction for C-H bond functionalization
Functionalization of hydrocarbons via a free-radical based allyl transfer reaction using various allyl bromide substrates has been previously studied. The work described in this dissertation focuses on the replacement of Br by phthalimido-N-oxyl (PINO ) which helps make this chemistry …

I. Synthesis of Ascarosides for Chemical Biology Studies in Caenorhabditis elegans, II. A Photochemical Approach to Delavayine, and III. Remote Hydroxylation by Radical Translocation and Polar Crossover
… the development of a strategy for remote C-H functionalization using redox catalysis. The Tzo directing group was used to effect 1,6- and 1,7-hydrogen atom transfers from unactivated aliphatics. The resulting radicals were then oxidized by redox (or photoredox) catalysis to form a carbocation …
