Abstract

Schiff base; methyl 2-((5-chloro-2-hydroxybenzylidene) amino)-6-methyl-4,5,6,7-tetrahydrothieno[ 2,3-c] pyridine-3-carboxylate was synthesized by the reaction of methyl 2-amino-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c] pyridine-3-carboxylate with 5-chloro-2-hydroxybenzaldehyde in excellent yield. This compound was characterized by elemental analysis, NMR (H-1 and C-13-APT), FT-IR and X-ray diffraction methods. The electrochemical behavior of Schiff base was investigated using cyclic voltammetry (CV), controlled potential electrolysis and chronoamperometry (CA) techniques. The number of electrons transferred (n), diffusion coefficient (D) and standard heterogeneous rate constants (k(s)) were also determined by electrochemical methods.
