14.  Influence of the Solvent on the Electrochemical Behavior of 1H-3- Methyl-4-Ethoxycarbonyl-Benzylidene-Hydrazino-Pyrazole

Authors: L.V. Costea and V.N. Bercean


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.


Keywords: Cyclic voltammetry, Electrochemistry, Heterocycles, Nonaqueous solvents
