A vast number of quinones with great structural divergence are provided by nature and play a major role in the redox electron-transport chains of living system [1-3]. More complex quinonoic compounds are used extensively in medicine, especially as anticancer agents, and their activity stems from their special ability to undergo one-electron transfer reaction to form reactive radicals [4,5]. The electrochemical synthesis of catechols has been studied in the presence cycloheptylamine and cyclopropylamine as a nucleophile, using cyclic voltammetry. During recent years a number of methods have been developed to propose the mechanism of reaction between quinones and some nucleophiles, and many quinones been synthesized [6] . As part of our ongoing program to investigate the electrochemical behavior of catechols with nitrogen nucleophiles [7] because of importance of aminoquinones as biologically active compounds.
