Electrolysis of aromatic aldehydes, malononitrile and malonates in methanol in an undivided cell in the presence of double-mediator system NaBr-NaOAc afforded 3-substituted 2,2-dicyanocyclopropane-1,1-dicarboxylates in 40–60% yields.
                                    在未分隔的电池中,在双媒介体系NaBr-NaOAc存在下,在
甲醇中对芳香醛、
氰基
丙二酸和
丙二酸盐进行电解,获得了产率为40-60%的3-取代2,2-二
氰基
环丙烷-1,1-二
羧酸盐。
