Interaction of fluoroalkyl-containing ?-diketones with amines
摘要:
The composition of products of the interaction of asymmetric fluoroalkyl-containing beta-diketones with amines was studied. Mixtures of regioisomeric beta-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 beta-diketone, and the basicity of the amine. The major product is a beta-aminovinylketone in which the NH2 group is removed from the fluoroalkyl substituent. No beta-aminovinylimines, products of condensation involving two electrophilic centers, were observed.
