Polyfluorinated enol acetates

The synthesis of polyfluorinated enol acetates has been performed by reductive dechlorination of chloropolyfluoroketones with zinc in Ac2O.Under these conditions, hexafluoroacetone is preferably reduced at the carbonyl group. - Key words: polychlorofluoroketones; reductive dehalogenation; polyfluorinated enol acetates; synthesis; reactivity.

METHOD OF MAKING HYDROFLUOROCARBONS

A method of producing hydrofluorocarbons and methods of producing other commercially attractive compounds formed as by-products of hydrofluorocarbon production by using aldehydes as a principal reactant.

REDUCTIVE DEFLUORINATION OF HEXAFLUOROACETONE ANIL

Hexafluoroacetone anil smoothly adds methyllithium at the C=N bond but undergoes reductive defluorination upon the action of Grignard reagents or metallic zinc to give 2-phenylaminopentafluoropropylene.
