Abstract

Abstract : New, powerful photoreductant organic dyes are described. Abstract : Here we report the application of readily prepared and available coumarin dyes for photoredox catalysis, which are able to mimic powerful reductant [Ir(iii )] complexes. Coumarin derivatives9 and10 were employed as photoreductants in pinacol coupling and in other reactions, in the presence of Et3 N as a sacrificial reducing agent. As the electronic, photophysical, and steric properties of coumarins could be varied, a wide applicability to several classes of photoredox reactions is predicted.
