of cinnamate esters has been carried out by cathodic reduction of CC bond in an undivided cell equipped with Mg sacrificial anode and using MeCN saturated with CO2 as solvent. The yields and the ratio of mono- and dicarboxylicacids are strongly affected by various factors: cathodic material, current, charge, and temperature. The highest yield (78.9%) was obtained starting from ethyl cinnamate. Cyclic
