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.

The present invention provides a room-temperature molten salt that is obtainable by mixing two or more organic salts and that has a solidifying point lower than the solidifying point (or melting point) of any of the starting organic salts, a process for producing the same, and use of the same. Specifically, the present invention provides a room-temperature molten salt that comprises a mixture of two or more organic salts with different anionic moieties and different organic cationic moieties and that has a melting point lower than any of the individual organic salts, a process for producing the same, and use of the same.
