The use of photoredox catalysis for functionalization reactions is a novel approach in synthetic organic chemistry. Synthetic efforts in our lab focus on halogenation and benzylic peroxidation reactions. Peroxides are prevalent in drug molecules, commonly part of pharmacophores. Eosin Y is a low-cost, long-known dye molecule used for photocatalysis. Successful benzylic peroxidation reactions of 2-phenethylbromide, 3-methylacetophenone, and other phenylic compounds using the photocatalyst Eosin Y were confirmed via NMR analyses. The mechanism of photocatalysis by Eosin Y is being explored computationally using the General Atomic and Molecular Electronic Structure System (GAMESS) software. Through the application of several different levels of theory, ground- and excited-state potential energy surfaces may be investigated to uncover insights into the mechanistic action of Eosin Y as a photoredox catalyst.
