Copper-mediated effective synthesis of S-trifluoromethyl esters by trifluoromethylthiolation of acid chlorides

A mild and efficient copper-mediated trifluoromethylthiolation of acid chlorides using (bpy)CuSCF3 has been developed. A wide range of S-trifluoromethyl esters were synthesized in good to excellent yields and various functional groups, including cyano, ether, ester, halide, nitro, et al. were well tolerated.
