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.
