Procedure
The beta-diketones which are used in carrying out this invention can be prepared by perfluoroacylation of appropriate ketones by esters or acid chlorides of perfluorocarboxylic acids, as in the reaction of methyl perfluorocaprylate with methyl tertiary butyl ketone to make 1-perfluoroheptyl-3 tertiary butyl-1,3 propanedione. Or a methyl perfluoroalkyl ketone can be acylated by an appropriate carboxylic derivative, as in the reaction of methyl phenylacetate with methyl perfluoropentyl ketone to give 1-perfluoropentyl-3-phenyl-1,3-propanedione; or in order to have two perfluorinated groups in the eventual isoxazoline, a methyl ketone containing also a perfluoroalkyl group can be acylated by an ester of a perfluorinated carboxylic acid, as when methyl perfluorocaprylate is reacted with methyl perfluoroheptyl ketone to produce 1,3-di(perfluoroheptyl)-1,3-propanedione.
