Abstract

In the present study, six newly synthesized 1,4-dihydropyiridine (DHP) derivatives (isopropyl 2,7,7-trimethyl-5-oxo-4-phenyl-1,4,5,6,7,8-hexahydroquinoline-3-carboxylates) (DM1-DM6) have been studied in water/ethanol mixture (50/50 v/v) by cyclic voltammetry, choronoamperometry and differential pulse voltammetry techniques at a glassy carbon electrode. A detailed oxidation mechanism is proposed. It involves an irreversible diffusion controlled one electron process followed by a disproportionation reaction resulting in the formation of a pyridine. Kinetic and thermodynamic parameters such as charge transfer coefficient (proportional to
