Summary.1H-3-Methyl-4-ethoxycarbonyl-5-(benzylidenehydrazino)pyrazoles are key intermediates in obtaining various heterocyclic systems including pyrazolotriazoles. We present the voltammetric behavior of these compounds in nonaqueous media, with the following para substituents grafted on the benzene ring: –N(CH3)2, –OH, –OCH3, –F, –Cl, –CF3, –NO2, as well as of the novel compounds with –Br, –I, and –SCH3 in the para position, in order to elucidate the influence of the various substituents on the mechanism of anodic oxidation.

The voltammetric behavior of 1H-3-Methyl-4-ethoxycarbonyl-5-(benzylidenehydrazino)pyrazoles in nonaqueous media reveals the influence of various substituents on anodic oxidation mechanisms.
