Electrochemistry provides very versatile means for the electrosynthesis, mechanistic and kinetic studies. Electrosynthesis has become more and more important in organic chemistry due to its following characteristics: unique selectivity because of in situ formation of an active species at the interface, inversion in polarity by transfer of electron and variability in product formation by control of potential. The most dominant advantage of using this chemical reagent is its adaptability to technology and flexibility in use. The use of water or ionic liquids instead of toxic solvents, room temperature condition, high energy efficiency and using the electrode as electron source instead of toxic reagents are in accord with the principle of green chemistry. The main goal of the electrochemical studies is the elucidation of the sequence of electron transfer and chemical reactions that occur near the electrode surface and their applications to electrosynthesis of organic compounds. On the other hand, diarylsulfones are important synthetic targets. They are useful in the practice of medicinal chemistry. Some of diphenylsulfones have been shown to inhibit HIV-1 reverse transcriptase.1,2 Among the numerous methods to synthesize diarylsulfones, Michael-addition reactions play an important role. In this context, as a part of a program to electrochemical synthesis of novel compounds based on the insitu generation of Michael acceptor using electrochemical reduction3, electrochemical behavior of 2-naphthol orange in aqueous solution in the presence of arylsulfinic acids has been studied. The present work has led to the development of a facile and environmentally friendly reagent-less electrochemical method for the synthesis of some new 1-amino-2-naphthol derivatives in aqueous solutions
