An efficient approach to β-trifluoromethyl-α,β-enones via oxidation of 4-aryl-1,1,1-trifluorobut-2-en-2-yl
trifluoromethanesulfonates is described. The reaction proceeds smoothly under mild
and metal-free conditions and tolerates a wide range of functional groups. Various
β-trifluoromethyl-α,β-enones were obtained in moderate to good yields.
