Electrochemical investigations on nitro-substituted hydrazono compounds
Abstract
The electrochemical reduction of 3-(N-nitro-N-phenylhydrazono)pentane-2,4-diones has been studied over a wide pH range at dropping mercury and glassy carbon electrodes. These compounds give two four-electron waves corresponding to the reduction of nitro and hydrazono groups, and one two-electron wave corresponding to the C–N reductive bond. On the basis of polarography, linear and cyclic sweep voltammetry, coulometry, IR, mass, and 1H NMR spectral studies, and product identification, a reaction mechanism is suggested to account for the reduction mechanism.
