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 5–51% 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
