摘要：

Here we report the application of readily prepared and available coumarin dyes for photoredox catalysis, which are able tomimic powerful reductant [Ir(III)] complexes. Coumarin derivatives 9 and 10 were employed as photoreductants in pinacol coupling and in other reactions, in the presence of Et3N as a sacrificial reducing agent. As the electronic, photophysical, and steric properties of coumarins could be varied, awide applicability to several classes of photoredox reactions is predicted.
