An efficient method for the Cu(I)-catalyzed synthesis of a-trifluoromethyl ketones via the addition of CF3 to aryl(heteroaryl) enol acetates by using the readily available CF3SO2Na (Langlois reagent) has been developed. The reaction is experimentally simple and carried out at room temperature, providing good to excellent yields with wide functional group tolerance. (C) 2014 Elsevier B.V. All rights reserved.
