Abstract

The formation of (1-ethyl-2-phenyl-1,4-dihydroquinolin-4-yl)-(2,4,6-trimethylphenyl)-amine by
the electro reduction of (1-ethyl-2-phenyl-1H-quinolin-4-ylidene)-(2,4,6-trimethylphenyl)-amine occurs
through acceptance of two electrons accompanied by two successive peaks, each electron peak followed
by a chemical reaction. The electrochemical reduction of (1-ethyl-2-phenyl-1H-quinolin-4-ylidene)-
(2,4,6-trimethyl-phenyl)-amine was investigated in 0.1 M tetrabutylammoniumbromide in N,N-dimethylformamide
at glassy carbon electrode using the technique of cyclic voltammetry at the room temperature
(290K). In this medium the first peak was observed at –0.831 V (vs. Ag|Ag+) at the glassy carbon electrode
(GCE) surface, which is more stable and well defined as compared to the second peak. The diffusion
coefficient (D) of investigated imine in the investigated solvent media has been calculated using the modified
Randles-Sevcik equation. The electron transfer coefficient (α) of the reactant species has also been
calculated. (doi: 10.5562/cca1855)
