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

Authors


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.
