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/cm2, benzophenone (1a) (8.2×10−3mol), electrolyte(KI, 1.7×10−2mol) in DMF (50

Synthesis of α-Hydroxycarboxylic Acids from Various Aldehydes and Ketones by
Direct Electrocarboxylation: A Facile, Efficient and Atom Economy Protocol
In present work, the formation of α-hydroxycarboxylic acids have been described from various aromatic aldehydes and ketones via direct electrocarboxylation method with 80-92% of yield without any side product and can be purified by simple recrystallization using sacrificial Mg anode and Pt cathode in an undivided cell, CO2 at (1 atm) was continuously bubbled in the cell throughout the reaction using
