Generation of Alkyl Radicals Via C-H Functionalization and Halogen Atom Transfer Processes
… first is C-H bond functionalization via hydrogen-atom-transfer (HAT). HAT processes have been used as an effective approach for selectively activating C-H bonds via radical pathways. The other strategy to explore the generation of alkyl radicals is C-X bond functionalization via …

Excited-state organic chemistry: Tuning photoprotective and photoredox properties
… of photoredox catalysis, a systematic study of halogen atom transfer (XAT) processes from phenyl and cyclohexyl halides using four representative α-aminoalkyl radicals and the parametrization of a library of 100 boryl radicals using Density Functional Theory (DFT). Chapter 6 describes the …

Decarboxylative Transformations Facilitated via Intermolecular Halogen Transposition using gem-Bromonitroalkanes
… merger of decarboxylation with intermolecular halogen transposition using gem-bromonitroalkanes. A systematic investigation of this novel synthetic framework enabled mild, green, and efficient conversion of carboxylic acids into electron-deficient styrenes, enamides, and β-nitroamines.

A Radical Approach to Photochemical Transformations Using Earth-Abundant Metals
… a bimolecular outer-sphere single electron transfer (OSET) process for the generation of open-shell radical species. While powerful, the efficiency of this approach is limited by the bimolecular diffusion rate of reactants and photocatalysts and a redox-potential matching requirement for …
