Electrochemical reduction of o-nitrotoluene at glassy carbon and stainless steel electrode at different pH

Abstract

The voltammogram of o-nitrotoluene (aqueous-methanol solution) in BR buffer at different pHs, 4.0, 7.0 and 9.0 exhibits the one reduction peak and effect of scan rate on cathodic peak potential indicates these reactions are irreversible. Constant current electrolysis in acidic and basic media of o-nitrotoluene gives o-toluidine and 2,2-dimethylazo-benzene respectively as a major products which were confirmed by TLC, NMR, IR spectrum analysis.
