Email: singhrkp1@gmail.com, rkp.singh@rediffmail.com Abstract A simple and efficient method for the convenient synthesis of aminoquinones have been described on reaction with catechol and various secondary amines using lithium perchlorate as a supporting electrolyte in acetonitrile media at platinum electrode under constant potential electrolysis.. The method is cost-effective, high-yielding, clean, and selective. The products of electrosynthesis have been purified and characterized by FTIR, 1HNMR, 13CNMR and mechanism was deduced with cyclic voltammetric study. Keywords: Anodic oxidation, cyclic voltammetry, electrochemical synthesis, o-benzoquinone secondary amines. 1. Introduction: The anodic oxidation of a catechol generates a reactive o-benzoquinone that can be used to trigger a number of interesting reactions [1-5] and play an important role in the redox electron transport chains of living systems [6-8] for example, vitamine K is known to play an important role in blood coagulation mechanism and also in photosynthesis, vitamine E is important factor in electron transport and oxidative phosphorylation.
