Five model 1-phenyl-3,3-dialkyltriazenes (methyl, ethyl, 2-propyl, butyl, cyclohexyl) have been synthesized and their acid-catalyzed decomposition kinetics have been investigated spetrophotometrically in aqueous ethanol (40 vol.percent) with pivalic acid as the catalyst.The results show that the rate-determining step is catalyzed by the proton.The decrease in the observed rate constant at higher concentrations of pivalic acid is explained by the formation of an unreactive complex of the nondissociated acid and respective triazene.The steric effect of alkyl groups on the catalytic rat constants is discussed.
