چکیده

Electrochemical oxidation of hydroquinone, catechol, and some of their monosubstituted derivatives has been studied in the presence of 3-hydroxy-1H-phenalen-1-one (2) as a nucleophile in water/acetonitrile (80/20) solutions using cyclic voltammetry and controlled-potential coulometry methods. The results revealed that quinones derived from oxidation of hydroquinones and catechols participate in Michael addition reactions with 2. The formed adducts convert to the corresponding benzofuran derivatives via different mechanisms. In this work, we derived a variety of products with good yields using controlled potential electrochemical oxidation at a graphite electrode in an undivided cell.
