DEVELOPMENT AND APPLICATION OF EARTH ABUNDANT METALS IN (METALLA)PHOTOREDOX CATALYSIS

Abstract

Earth-abundant metals in methodology development. Novel catalytic methods that enable the selective functionalization of organic molecules are of high value to synthetic chemists. While traditional catalytic methodologies rely on the reactivity of rare-earth metal catalysts, a significant advance, economically and environmentally, would be the development of challenging bond forming methods utilizing earth-abundant metals, such as iron, manganese, and cobalt. Metallaphotoredox centers around the combination of photocatalytic and transition metal catalytic cycles to enable bond formations. By the development of alternative earth-abundant photocatalysts using cobalt (Chapter 2), and the use of manganese in the merger of MHAT and photoredox catalysis (Chapters 3, 4), significant advances have been made to increase the economic and environmental attractiveness of metallaphotoredox.
