Electrochemical studies on arylhydrazonomesoxalonitriles in nonaqueous media

Abstract

The substituted arylhydrazonomesoxalonitriles and N-methyl phenylhydrazonomesoxalonitrile are studied electrochemically in benzonitrile (BN) employing different voltammetric and coulometric techniques. They are oxidized in a single irreversible one-electron transfer leading to a dimerization reaction. The reduction process occurs in two irreversible one-electron uptakes followed by proton abstraction from the solvent to give the saturated azomethine linkage.
