The reactions of heptafluoro-1-methylethylzinc iodide (1) with fluorides or anhydrides of carboxylic acids were smoothly induced in the presence of pyridine, and aryl or alkyl heptafluoro-1-methylethyl ketones were obtained in good yields. Although the reactivities of benzoyl halides in this reaction were in the order PhCOF> PhCOCl> PhCOBr, benzoyl chloride reacted with 1 smoothly in the presence of zinc fluoride, which converted benzoyl chloride to fluoride in situ.
