Regioselective conjugate 1,4-trifluoromethylation of alpha, beta-unsaturated ketones by the use of shelf-stable electrophilic trifluoromethylating reagents, S-(trifluoromethyl)diphenylsulfonium salts and copper under mild conditions is described. A wide range of acyclic aryl-aryl-enones and aryl-alkyl-enones were converted into beta-trifluoromethylated ketones in low to moderate yields.
