  Herein, we report an electrochemical protocol for the dicarboxylation of aryl alkynes using CO2. With a graphite rod as the cathode and Al as the sacrificial anode, a series of valuable butenedioic acids are obtained in moderate to excellent yields with an E/Z ratio up to 50:1. This method features high E-selectivity, high step and atom economy, easy scalability, and a nice substrate scope, which renders

  在此，我们报告了使用 CO 2芳基炔烃二羧化的电化学方案。以石墨棒为阴极，Al为牺牲阳极，以中等至优异的收率获得了一系列有价值的丁烯二酸， E / Z比高达50:1。该方法具有高E选择性、高步骤和原子经济性、易于扩展性和良好的底物范围，这使其在有机合成和材料化学中具有广阔的应用前景。
