Synthesis and electrochemical studies of 4-[(E)-(4-hydroxy-3-methoxybenzenylidine)amino)]-N-(substituted)benzenesulfonamide

School of Studies in Chemistry, Jiwaji University, Gwalior-474 011, Madhya Pradesh, India E-mail : rajeevjain59@yahoo.co.in, halveanand@yahoo.co.in, apoorva.phd12@gmail.com Manuscript received online 08 April 2015, revised 30 April 2015, accepted 01 May 2015 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.
