A method is proposed for the synthesis of fluorine-containing methoxy-1,3-diketones by hydrolysis of N-phenylaminoalkenyl ketones, produced by the reaction of aniline and the respective methoxyalkynyl ketone in dioxane. With methanol an imine is also formed, and methyl trifluoroacetate is eliminated.Institute of Chemical Kinetics and Combustion, Siberian Branch, Russian Academy of Sciences, 630090 Novosibirsk.
