Study of the Mechanisms of Reactions of 1,3-Dicarbonyl Compounds with Nucleophilic Reagents: X. Kinetics of the Hydrolysis of Methyl 4-Aryl-2-Arylamino-4-Oxobut-2-Enoates

The kinetics of hydrolysis of methyl 4-aryl-2-arylamino-4-oxobut-2-enoates in 50% aqueous dioxane in the presence of acetate and monochloroacetate buffer solutions was studied by spectrophotometry. An analysis of the dependence of the rate of hydrolysis on the concentrations and the composition of the components of the solutions and on the nature of the substituents in the substrate made it possible to propose a mechanism of general acid catalysis of the reaction.
