INTERACTION OF FLUOROALKYL-CONTAINING BETA-DIKETONES WITH AMINES

The composition of products of the interaction of asymmetric fluoroalk yl-containing beta-diketones with amines was studied. Mixtures of regi oisomeric beta-aminovinylketones and products of cleavage and secondar y condensation are formed, depending on the temperature, the solvent, the nature of the fluorinated and nonfluorinated substituents in the b eta-diketone, and the basicity of the amine. The major product is a be ta-aminovinylketone in which the NH2 group is removed from the fluoroa lkyl substituent. No beta-aminovinylimines, products of condensation i nvolving two electrophilic centers, were observed.
