摘要

The electrochemical dicarboxylation of arylacetylenes with carbon dioxide could be smoothly achieved in an undivided cell using Ni as the cathode and Al as the anode with n- Bu4NBr–DMF as the supporting electrolyte, at a constant current under CO2 pressure of 3MPa and room temperature in the absence of additional catalysts. The corresponding aryl- maleic anhydrides and 2-arylsuccinic acids were afforded in excellent total yields (82–94 ...
