Synthesis of (1-ethyl-2-phenyl-1,4-dihydroquinolin-4-yl)-(2,4,6-trimethylphenyl)-amine by Electrochemical Methods in Aprotic Media

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-dimethyl- formamide 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 elec- trode (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 mod- ified Randles-Sevcik equation. The electron transfer coefficient (α) of the reactant species has also been calculated. (doi: 10.5562/cca1855)
