triflates was promoted successfully by potassium fluoride in dichloromethane at room temperature, giving β-perfluoroalkyl (Rf; CF3, C2F5, i-C3F7, n-C7F15) carbonyl compounds in good yields. An enol silyl ether of an α,β-unsaturated carbonyl compound gave a δ-Rf-α,β-unsaturated carbonyl compound selectively.
