| 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. |
