摘要

In an undivided cell, the electrocarboxylation of [(4-methoxy-benzylidene)-amino] - acetic acid esterbearing an aliphatic substituent on the amine fragment was first investigated in the DMF solutionunder the atmospheric pressure of carbon dioxide using magnesium rod as the sacrificial anode. As aresult, C-carboxylated, N-carboxylated and C,N-dicarboxylated products were isolated as their methylesters whose yields were influenced by various reaction conditions including the supportingelectrolyte, cathode material, current density, charge passed and temperature. Using glassy carbon asthe working electrode, the electrochemical behavior of the aryl alkyl substrate was studied by cyclicvoltammetry. Based on the character in the absence and presence of carbon dioxide, the possibleelectrocarboxylation mechanism was postulated accordingly.
