Oxidative Radical Intermolecular Trifluoromethylthioarylation of Styrenes by Arenediazonium Salts and Copper(I) Trifluoromethylthiolate

An efficient oxidative radical intermolecular trifluoromethylthioarylation of styrenes with arenediazonium salts and copper­(I) trifluoromethylthiolate under mild conditions is described for the first time. The reactions provide good yields of the corresponding trifluoromethylthioarylation products with broad substrate scope and excellent functional group compatibility.
