Abstract

Electrochemical oxidation of catechols (1a–c) has been studied in the presence of 3‐mercapto‐1,2,4‐triazole (3) as a nucleophile in water/acetonitrile (90/10) solutions. The results revealed that the quinones derived from catechols (1a–c) participate in the Michael addition reactions with anion of 3‐mercapto‐1,2,4‐triazole (3) and are converted to the corresponding (1H‐1,2,4‐triazol‐3‐ylthio)benzen‐1,2‐diol derivatives (4a–c). © 2007 Wiley Periodicals, Inc.
