Electrolysis of malononitrile and carbonyl compounds in the presence of alkali metal halides in an undivided cell results in the formation of substituted 1,1,2,2-tetracyanocyclopropanes in 60–90% yield. This electrocatalytic variant of the Wideqvist reaction using malononitrile instead of bromomalonitrile was successfully performed. Electrocatalytic transformation of substituted 1,1,2,2-tetracyanocyclopropanes
在不分开的电解槽中,在碱金属卤化物存在下,丙二腈和羰基化合物的电解导致取代的1,1,2,2-四氰基环丙烷的形成,产率为60-90%。使用丙二腈代替溴丙二腈成功进行了Wideqvist反应的这种电催化变体。在未分开的电池中,甲醇或乙醇中取代的1,1,2,2-四氰基环丙烷的电催化转化导致取代的2-氨基-4,4-二烷氧基-1,5-二氰基-3-氮杂双环[3.1.0] hex-通过0.05-0.10 F / mol的电量后,二烯的产率为70-95%。
