Aroyl chlorides as novel acyl radical precursors via visible-light photoredox catalysis

Abstract

Abundant and inexpensive aroyl chlorides have been employed for the first time as novel acyl radical precursors in visible-light photocatalysis. This radical cascade reaction building new C–C bonds is an effective way to synthesize valuable heterocyclic compounds. This approach mainly features a concise redox-neutral mechanism, radical cascade reaction, mild conditions and convenient operations.
