Aroylchlorination of 1,6-Dienes via a Photoredox Catalytic Atom-Transfer Radical Cyclization Process

Abstract

A method using aroyl chlorides as atom-transfer radical cyclization agents in a novel visible-light photocatalytic aroylchlorination reaction is developed. The overall transformation involves the formation of two new C-C bonds and one new C-Cl bond in a one-pot process. The advantages of this reaction include high atom/step/redox economy, mild conditions, operational simplicity, and broad substrate scopes.
