Esters of oxalic acid, 3,4-dihydroxy-3-cyclobutene-1,2-dione (squaric acid), and oxamic acid, are reduced cathodically at modest potentials. In aprotic solvent, and on the cyclic voltammetric time scale, the esters are cleaved to the corresponding alkane. For oxalates, the mechanism of cathodic cleavage was investigated thoroughly by voltammetry, coulometry, and detailed product analysis. On the time
草酸,3,4-二羟基-3-环丁烯-1,2-二酮(方酸)和草酰胺的酯在中等电位下被阴极还原。在非质子溶剂中,并在循环伏安时间范围内,将酯裂解成相应的烷烃。对于草酸盐,通过伏安法,库仑法和详细的产品分析对阴极裂解的机理进行了深入研究。在受控电位电解的时间尺度上,不定水快速电催化生成的酯进行碱催化的水解与阴极裂解竞争。类似地,观察到涉及草酸酯和添加的醇的快速碱催化的酯交换反应,这提供了一种通过将醇与易得的草酸酯(例如草酸二乙酯)的混合物进行共电解而将醇还原裂解为烷烃的实用方法。
