Electrochemical methods are widely used for the study of electroactive compounds in pharmaceutical forms and physiological fluids due to their simple, rapid, and economical properties [1]. 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 are some of advantage of electrosynthesis. Michael addition reaction, as a one of the effective organic reaction, has been shown its importance during last years. Electrochemical oxidation of 2,2'-biphenol has been studied in the presence of arilsulfinic acids as nucleophile using cyclic voltammetry and controlled-potential coulometry methods.
