aliphatic carboxylic acids or substituted benzoic acids with an electron-donating group gave ketones in high yields. The above-mentioned aromatic compounds were also acylated with N-trifluoroacetylimidazole and free carboxylic acids in trifluoroaceticacid. The mechanism for these reactions was assumed to proceed via a mixed anhydride between trifluoroaceticacid and carboxylic acid.
