Using Ni cathode and Al sacrificial anode, the electrocarboxylation of polycyclic aromatic hydrocarbons (naphthalene, 5‐methylnaphthalene, anthracene, phenanthrene and 1H‐indene) with carbon dioxide (4 MPa) could be successfully performed in an undivided cell containing n‐Bu4NBr‐DMF supporting electrolyte with a constant current at room temperature, affording the corresponding trans‐dicarboxylic acids
使用Ni阴极和Al牺牲阳极,可以在含n Bu 4 NBr的不分隔电池中成功地进行多环芳烃(萘,5-甲基萘,蒽,菲和1H-茚)与二氧化碳(4 MPa)的电羧化‐DMF在室温下以恒定电流支持电解质,以良好至极好的收率(62%–90%)提供相应的反式二羧酸。在所检查的阴极材料(Ni,Pt,Ag,Cu和Zn)中,Ni和Pt阴极对电羧基化表现出良好的催化活性。此外,实验结果表明,电解条件(导电盐,电,CO 2压力和温度)也会影响电羧化的结果。根据电羧基化和CV(循环伏安法)的结果,还提出了可能的电化学反应机理。
