A facile synthetic procedure for the preparation of α-trifluoromethyl carboxylic acids and esters was achieved through multicomponent coupling reactions between gem-difluoroalkenes, cesium fluoride, and carbon dioxide. The products were generated in moderate to excellent yields, and the synthetic utility of this method was demonstrated through the preparation of trifluoromethylated versions of popular nonsteroidal anti-inflammatory drugs (NSAIDs).
Process for producing α-(trifluoromethyl)arylacetic acid

, (2008/06/13)
α-(trifluoromethyl)arylacetic acid for use as raw materials for medicines, agricultural chemicals, liquid crystals etc. or reagents for determining an optical purity is readily obtained through very simple reaction steps, i.e. by reacting a perfluoro(2-methyl-1,2-epoxypropyl)ether compound obtainable by ozone, oxidation of a heptafluoroisobutenyl ether compound with an aromatic compound ArH to afford an α,α-bis(trifluoromethyl)arylacetic acid ester, followed by decarboxylation and hydrolysis of the resulting ester compound.

The hitherto unknown α-(trifluoromethyl)phenylacetonitrile has been synthesized by reduction of the cyanohydrin of α,α,α-trifluoroacetophenone.Sodium borohydride reduction of the corresponding cyanohydrin tosylate resulted in reductive decyanation in dimethyl sulphoxide and in reduction of the nitrile group in t-butanol. - Keywords: Synthesis; α-(Trifluoromethyl)phenylacetonitrile; Anomalous reactions; Sodium borohydride; NMR spectroscopy; IR spectroscopy, Mass spectrometry
