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

Abstract

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)

Synthesis, Theoretical and Experimental Investigation of Electronic Properties of New Fluoranthenyl‐Based Compounds for OLEDs Applications

“…EEM spectroscopy allows for simultaneous variation of both excitation and emission wavelengths, providing a comprehensive map of the entire fluorescence landscape compared to the limited information from one‐dimensional spectra. The relationship between the maximum emission wavelength and the fluorescence intensity of the compounds is closely related to the polarity of their environment [31] . Figure 10 illustrates the 3D spectra contour maps for EIF, TIF and FIF.…”

Novel Approach for the Cyclic Voltammetric Determination of an Antidepressant Drug (Dosulepin) in Pharmaceutical Formulations

“…The scan rate was increased from 5 to 100 mV/s at a constant dosulepin dosage, and the following findings were made: (a) the peak potential (E P ) altered cathodically, (ii) the peak current (i p ) steadily rose, and (iii) i p / ACυ 1 / 2 which represented the peak current function exhibited near-constancy. [22][23][24][25][26][27][28] Peak current (i p ) is displayed against by the square root of scan rates (υ 1 / 2 ) (Figure 3), yielding a straight line that may be described by the equation.…”

Determination of ultra-trace amounts of neonicotinoid insecticide imidacloprid by cyclic and square wave voltammetric methods using pretreated glassy carbon electrode

“…Moreover, it is known that a rate-determining electron transfer is always a one-electron process (na = 1) and α generally varies between 0.3 and 0.7 (Kumari and Sharma, 2011a;Kumari and Sharma, 2011b). From the slope of eq.…”
