External‐Oxidant‐Free Electrochemical Oxidative Trifluoromethylation of Arenes Using CF₃SO₂Na as the CF₃ Source

Abstract

Summary of main observation and conclusion An efficient and environmentally benign electrochemical oxidative radical C—H trifluoromethylation of arenes by employing Langlois reagent as the CF 3 source was developed in this work. Neither transition metal catalysts nor external chemical oxidants were required in this trifluoromethylation process. The reaction could be conducted in gram scale with high reaction efficiency.
