Sodium Salts Dissolution in an Aprotic Solvent by Coordination of Poly(ethylene glycol) for Effective Anodic Reactions of Organic Compounds

Abstract

The electrochemical oxidation of various organic compounds using inorganic salts like sodium halides and sodium tetrafluoroborate has been accomplished under mild conditions. The long-standing problem of solubility of inorganic salts in aprotic organic solvents in electroorganic synthesis has been overcome by the addition of poly(ethylene glycol) to the electrolytic solutions through cyclic voltammetry analysis and macro-scale electrolysis. By using this method, anodic halogenation, anodic deprotection, and anodic coupling reaction of organic compounds were successfully carried out to provide desired products efficiently.
