Perfluoroalkylcadmium complexes react with aroyl halides in the presence of strong bases such as pyridine to give the corresponding ketones ArCORf (which can be isolated in 5-51percent yield) and (perfluoroalkyldihydropyridine)aroylamides.The pure substances are obtained by chromatography.Aroyl fluorides and α,α-bis(trifluoromethyl)benzyl alcohols and benzoic acid-α,α-bis(trifluoromethyl)benzyl esters can be isolated as by-products.The dependency of the products formed on the kind of bases used as well as the reaction mechanisms are described.All products were identified by their 19F, 1H, 13C NMR, mass and IR spectra, and by elemental analysis.
