Direct Synthesis of Diphenyl Carbonate by Electrocarbonylation at a Pd2+-supported Anode
The first electrochemical synthesis of diphenyl carbonate was accomplished using triethylamine/tetrabutylammonium perchlorate/phenol/dichloromethane or sodium phenoxide/phenol/acetonitrile electrolyte at a [PdCl2/activated carbon and vapor grown carbon fiber] anode, 1 atm CO and 25 degrees C. Sodium phenoxide functioned as a promoter, triethylamine, and a supporting electrolyte, tetrabutylammonium perchlorate, for the carbonylation.
