Introduction
Water is one of the most ideal solvents for electrolysis because water has a high dielectric constant and can dissolve many salts (supporting electrolyte). Water is readily available, safe (incombustible, nontoxic, etc.), and environmentally benign. However, water has some disadvantages as a medium for electrolysis. Potential window of water is narrower than organic solvents, and electrolysis of water occurs as a side reaction. Moreover, many organic substrates and organic mediators (electrochemical catalysts) are insoluble in water. Therefore, highly polar organic solvents, such as DMF and DMSO, and/or two-phase systems consisting of water-organic solvents, e.g., water-CH2Cl2 and water-AcOEt, have been used for electrolysis.
Examples of Electrosynthesis Using Water Suspension System
To overcome these disadvantages and obtain high current efficiency for the desired products in water, several methods have been developed. For instance, electrolysis has been performed (1) in...
