The reactions of trifluoromethyl ketones with enamines or imines are described. The reaction of trifluoroacetone with enamines or imines followed by hydrolysis gave the corresponding beta -hydroxy-beta -trifluoromethyl-beta -methyl ketones in good yields. The reaction of trifluoromethylated beta -diketones with enamines in the presence of ammonium acetate gave 4-trifluoromethylated pyridines exclusively in good yields, without any detectable amount of regioisomers.
