Some new 4-[(E)-(4-hydroxy-3-methoxybenzenylidine)amino)]-N-(substituted)benzenesulfonamides were synthesized by condensation between aldehyde with different sulphanalamide derivatives. Electrochemical behaviour of 4-[(E)-(4-hydroxy-3-methoxybenzenylidine)amino)]-N-(substituted)benzenesulfonamides have been studied in Britton-Robinson buffers of pH 2.5–12.0 at dropping mercury electrode. All benzenesulfonamides gave one electron wave corresponding to the reduction of -C=N- bond at mercury electrode. On the basis of differential pulse polarography, IR, mass and ¹H NMR spectral studies and product identification, a reduction mechanism has been suggested.
