acetonitrile with alkali metal fluorides. Other products identified in hydrolyzed reaction mixtures include perfluoroolefins and monohydroperfluoro compounds. A mechanism involving the formation of a carbanion intermediate is proposed. Evidence for the formation of carbanions has been obtained by carrying out the reaction in the presence of bromine and also in the presence of other substrates.

Perfluorocarboxylic acid salts of a monovalent metal are reacted with perfluorocarboxylic acid fluorides in aprotic polar solvents. Perfluoroketones are obtained. The salt of the perfluorocarboxylic acid can be replaced by alkali metal salts of formic acid, oxalic acid or of oxygen-containing mineral acids, the central atom of which is an element of the groups IIIA to VIIA of the periodic table and which mineral acid is weaker than trifluoroacetic acid. The same result is obtained if the anhydride of the perfluorocarboxylic acid is contacted with an alkali metal fluoride. The synthesized perfluoroketones are liquids of high chemical and thermal stability.
