Title :

Stable Radical Anions in Photocatalysis

Abstract :

In the recent past visible light photoredox catalysis has gained enormous attention as an energy-efficient and versatile method for chemical synthesis.(1, 2) In my presentations, I will mainly talk about our recent work on visible light photoredox catalysis using stable radical anions of commercially available inexpensive organic dyes.(3-7) The applications of bioinspired consecutive photoinduced electron transfer (conPET)(3, 4, 6, 7) and sensitization initiated electron transfer (SenI-ET)(5) processes will be discussed in the context of breaking and making of stable chemical bonds for useful synthetic transformations.
