Electrochemistry of the Solvated Electron: A Study of Its Properties and of ItsApplications

摘要

The electrochemistry of solvated electrons is discussed. The electrochemicalgeneration of solvated electrons in hexamethyl phosphortriamide (HMPA) and in methylamine was investigated. Lithium chloride or lithium bromide was used as the elecrolyte. Because the rotating ring disk electrode (RRDE) technique was used in particular, this technique is described. Attention is paid to the merits of solvated electrons as a powerful reductant in electroorganic synthesis. In HMPA/Li salt solutions, solvated electrons can be cathodically generated at the disk of a RRDE and be oxidized when they reach the ring electrode. The use of this hydrodynamic technique to study several features of electrochemistry is described. It was shown that by means of transit time measurements, information can be obtained about the mobility of solvated electrons in HMPA/Li salt solutions. The reaction of solvated electrons with water and benzene is described. It is shown that various substituted benzylamines can be reduced in methylamine using lithium chloride as electrolyte.
