Abstract

Abstract: The kinetics of aminolysis of 11 phenyl esters by various amines have been studied spectrophotometrically under pseudo-first-order conditions in anhydrous p-dioxane. The following relationships were found: kobsd= k2 (arnine) f ka (amine) 2 for the reaction of phenyl dichloroacetate with n-butylamine and 3-methoxy-npropylamine, and for the reaction of phenyl difluoroacetate with n-butylamine; kobsd= kn (amine) for the reaction of phenyl ...
