Harnessing immobilized copper salophen complex for the electrochemical synthesis of phenazine

This study introduces a novel approach utilizing a modified electrode, denoted as Cu-PDABA-CFP, as a pivotal catalyst in the electrochemical synthesis of phenazine. Through bulk electrolysis of o-phenylene diamine in an acetonitrile medium, facilitated by lithium perchlorate as the supporting electrolyte, the electrode serves as a fundamental component in this synthetic endeavor. The modification process entails the immobilization of a copper-salophen complex, synthesized in accordance with established literature protocols, onto the electrode surface. Surface characterization of the modified electrode was meticulously conducted to get critical insights into the structural morphology and topographical features of the electrode surface, pivotal for understanding its electrochemical behavior. Concurrently, electrochemical characterization studies were undertaken to evaluate the inherent activity of the modified electrode. To elucidate the intricate electrochemical reaction mechanism underlying the synthetic transformation, an exhaustive screening of reaction conditions was meticulously undertaken. The findings presented herein contribute not only to advancing our fundamental understanding of electrochemical processes but also hold promise for the development of novel electrochemical methodologies with broader applicability in synthetic chemistry and materials science.
