in MeOH in the presence of alkali metal halide as mediator, leads to the formation of cyclic dimers, i.e., 3,4-disubstituted 1,1,2,2-cyclobutanetetracarboxylates. The reaction proceeds via the reductive coupling of two substrate molecules at cathode and the cyclization of a hydrodimer dianion by its interaction with an active form of a mediator, an anode-generated halogen.
在碱金属卤化物为介体的情况下,在未拆分的MeOH电解槽中,在未分隔的单元中电解亚烷基亚甲基丙二酸二甲酯RCH = C(COOMe)2(R = n-Alk,Ph),导致形成环状二聚物,即3,4-二取代的1,1,2,2-环丁烷四羧酸盐。该反应通过阴极上两个底物分子的还原偶联和氢二聚体二价阴离子通过与介体的活性形式(阳极产生的卤素)的相互作用而环化来进行。
