Electrochemical oxidation of phenylhydrazine has been carried out in the presence of ɑ- and β- naphthol as nucleophiles in acetonitrile/ buffer mixture (30/70) in different pHs with employing the cyclic voltammetry and controlled potential coulometry methods. The results indicate that the phenylhydrazine oxidizes at the surface anode and participates in Michael-type reaction with ɑ- and β- naphthol to form the corresponding new naphthol derivatives. In this work, some new naphthol derivatives have been obtained with good yields based on the electrochemical oxidation in the controlled potential situation, without toxic reagents and solvents, at the carbon electrode, and in an undivided cell.
