The composition of products of the interaction of asymmetric fluoroalkyl-containing β-diketones with amines was studied. Mixtures of regioisomeric β-aminovinylketones and products of cleavage and secondary condensation are formed, depending on the temperature, the solvent, the nature of the fluorinated and nonfluorinated substituents in the β-diketone, and the basicity of the amine. The major product is a β-aminovinylketone in which the NH2 group is removed from the fluoroalkyl substituent. No β-aminovinylimines, products of condensation involving two electrophilic centers, were observed.
