Abstract
Fifteen substituted derivatives of 3-(N-methylcarbamoyl)-1,3-diphenyltriazene and nine substituted derivatives of 3-(N-phenylcarbamoyl)-1,3-diphenyltriazene have been synthesized. With 22 derivatives kinetic measurements have been carried out in acid, neutral and alkaline regions, and the respective catalytic constants have been determined. From the kinetic results the Hammett reaction constants have been calculated and used for discussion of the reaction mechanism suggested earlier.
