Functionalization of Carbonyl Compounds via Photoredox Organocatalysis

In recent years, a methodology merging photoredox catalysis with organocatalysis termed “photoredox organocatalysis” has emerged to allow the direct, selective and efficient functionalization of the α/β‐C of carbonyl compounds under mild reaction condition. In this review, photophysics background of photoredox catalysis is introduced, followed by a report on recent advances in direct α‐ and β‐functionalization of carbonyls with photoredox organocatalysis methodology. With this different reaction modes, valuable synthetic targets including different α/β‐functionalized carbonyls are accessible.
