Production of butane tetracarboxylic acid derivative by means of coupled electrosynthesis
摘要：
A process for preparing butanetetracarboxylic acid derivatives as product of value I by coupled electrosynthesis which comprises cathodically reducing a compound selected from the group consisting of maleic esters, maleic ester derivatives, fumaric esters and fumaric ester derivatives where at least one hydrogen atom in positions 2 and 3 may be replaced by inert groups and obtaining a product of value II at the node.
摘要（中）：

通过偶联电合成制备丁酸四羧酸衍生物作为值I的产物的方法，其包括阴极还原选自马来酸酯，马来酸酯衍生物，富马酸酯和富马酸酯衍生物的化合物，其中位置2和 3可以由惰性基团代替，并在节点处获得值II的乘积。
