Synthesis of Novel Chalcone Substituted Metallophthalocyanines: Electrochemistry, Spectroelectrochemistry and Catalytic Oxidation of 2-mercaptoethanol

Abstract

Novel metallophthalocyanines (M = Zn, Co) carrying on the four of the peripheral positions (E)-1-(furan-2-yl)-3-(4-hydroxyphenyl)prop-2-en-1-one as chalcone were sythesized. These complexes have been characterized by a combination of FT-IR, ¹H-NMR, HRMS and UV–Vis spectroscopy techniques. Also cyclic voltammograms of these phthalocyanines were taken and obtained knowledge as zinc phthalocyanine have one reduction reaction and cobalt phthalocyanine have two reduction reaction. Spectroelectrochemical investigation shows the ring based reduction of MPc’s. Pc-7 cobalt(II)phthalocyanine was investigated as catalyst in the catalytic oxidation of 2-mercaptoethanol. Turnover number, initial reaction rate and the oxygen consumption was found in the catalytic oxidation of 2-mercaptoethanol as 16.6,  0.29, 2.52 recpectively.
