Influence of the solvent on the electrochemical behavior of 1H-3-methyl-4-ethoxycarbonyl-benzylidene-hydrazino-pyrazole [articol]

Abstract

The electrochemical properties of 1H-3-methyl-4-ethoxycarbonyl-5-benzylidenehydrazino-pyrazole have been investigated in two different aprotic nonaqueous solvents, at a platinum electrode. The voltammetric investigation of the above compound in anhydrous acetonitrile (AN) and dimethylsulfoxide (DMSO) respectively shows a somehow similar behavior but significant differences are also noticeable. The different peak separation and peak height can offer supplemental information in order to get a clearer view of the mechanism governing the anodic oxidation of the latter compound and to find the proper parameters to synthesize pyrazolo-triazoles by electro-synthesis.
