The kinetics of hydrolysis of fluoroalkyl-containing beta-aminovinyl ketones R1C(O)CHC(NHR3)R2, in which the substituents CF3 and HCF2CF2 are in the ketone (R1) or enamine parts of the molecule (R2), was studied. In acid (pH < 5) and alkaline (pH > 10) media, they hydrolyze with the formation of the corresponding amines and beta-diketones. In an alkaline medium, the beta-diketones undergo cleavage to fluorinated acids and methyl ketones. The rate constants of hydrolysis in an acid medium change within a range of four orders, depending on the nature of the substituents. The presence of a fluoroalkyl group at the enamine reaction center increases the hydrolysis rate. In an alkaline medium, the rate constants vary within one order.
