Abstract

The kinetics of the n-butylaminolysis of three series of mono-and disubstituted phenyl N- phenylcarbamates 1-3 have been studied spectrophotometrically under pseudo-first-order conditions in dioxane. The relation koM= k2 [n-BuNH2]+ k3 [n-BuNH2I2 was found applicable for all esters. The rate constants k2 and k3 were correlated by the Hammett equation, and the corresponding activation parameters were determined. The reaction ...
