Highly efficient Cu(I)-catalyzed trifluoromethylation of aryl(heteroaryl) enol acetates with CF3 radicals derived from CF3SO2Na and TBHP at room temperature

CuI-catalyzed trifluoromethylation of aryl(heteroaryl) enol acetates using CF3SO2Na provided the corresponding α-trifluoromethyl ketones. The reaction is carried out at room temperature, providing good to excellent yields with broad substrate scope.
