With some common metal salts (CuI, FeCl3) as catalysts, alkynes can be effectively electrocarboxylated with CO2 (4 MPa) in an undivided cell with Ni cathode and Al sacrificial anode containing n‐Bu4NBr‐DMF as supporting electrolyte with a constant current at room temperature. The saturated tricarboxylic acids besides the dicarboxylic acids were obtained in good yields. The yields of the tricarboxylic
使用某些常见的金属盐(CuI,FeCl 3)作为催化剂,炔烃可在不分隔的单元中有效地被CO 2(4 MPa)电羧化,该单元具有Ni阴极和Al牺牲阳极,其中n - Bu 4 NBr-DMF作为辅助电解质,n在室温下保持恒定电流。除了二羧酸之外,还以良好的产率获得了饱和的三羧酸。三羧酸的收率受到各种金属盐催化剂,阴极材料和取代基性质的强烈影响。最后,讨论了可能的电化学机理。
