摘要

Reaction conditions for the electrochemical synthesis of benzilic acid (2a) under the atmosphere of carbon dioxide was investigated from the preparative points of view. The highest yield of 2a (86%) was obtained under the following conditions; cathode: mercury, electricity passed: 2.3 F/mol, constant current density: 2.5 mA/cm 2, benzophenone (1a)(8.2× 10− 3 mol), electrolyte (KI, 1.7× 10− 2 mol) in DMF (50 ml). This method and conditions ...
