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.

An efficient, mild, and metal-free approach to direct diazenylation of N-heterocyclic compounds with aryltriazenes using Br?nsted ionic liquid as a promoter has been developed for the first time. Many N-heterocyclic azo compounds were synthesized in good to excellent yields at room temperature under an open atmosphere. Notably, the promoter 1,3-bis(4-sulfobutyl)-1H-imidazol-3-ium hydrogen sulfate could be conveniently recycled and reused with the same efficacies for at least four cycles.

An efficient, fast and straightforward procedure for the synthesis of aryltriazenes is described in the present paper by using aryl diazonium silica sulfates and secondary amines. Using the present method, different kinds of aryl diazonium silica sulfates
