Abstract: This study presents synthesis of 3-[4'-(substituted) sulphonamoylphenyl] azomethine indoles (SPAI) by refluxing indole-3-carboxaldehyde with sulfonamide derivatives. Electrochemical behaviour of SPAI was studied in Britton-Robinson (BR) buffer solution (pH 2.5-12.0) at dropping mercury electrode (DME) and glassy carbon electrode (GCE). Cathodic differential pulse polarographic peak was obtained at DME in pH range 2.5-6.5. Cyclic voltammogram exhibited a well defined, irreversible cathodic and anodic peak at GCE. At pH 6.5 and above, reduction peak exhibited a tendency to split into two peaks, indicating that 1H+/2e- reduction of 2-[4’-sulphonamoylphenyl]hydrazono-1,3-indanediones occurs in one 1H+ and one 2e- steps. A product of CPE was characterized by elemental and spectral analyses.
