A novelsynthesis of perfluoroalkyl alkyl ketones via the hydrolysis of fluorinated β-ketophosphonium salts is described. In view of the fact that a one-pot reaction without isolation of intermediates and the total yield in 2 steps reaches 37-78%, the present method provides a convenient synthesis of the title compounds.

Trifluoromethylated beta,gamma-unsaturated esters and nitriles can be synthesized by reaction of organozinc compounds with fluorinated beta-ketophosphonium salts. This novel reaction without isolation of intermediates provides a convenient synthesis of the title compounds which may be useful intermediates for the preparation of fluorinated biologically active compounds.
