Sulfonation and Trifluoromethylation of Enol Acetates with Sulfonyl Chlorides Using Visible‐Light Photoredox Catalysis

Abstract

Abstract A mild, practical method to prepare α‐sulfonyl and α‐trifluoromethyl ketones from readily available enol acetates and sulfonyl chlorides has been developed using visible‐light photoredox catalysis. The method could be used with a wide range of enol acetates and sulfonyl chlorides, and gave the desired products in satisfactory to excellent yields.
