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 in methanol or ethanol in an undivided cell leads to substituted 2-amino-4,4-dialkoxy-1,5- dicyano-3-azabicyclo[3.1.0]hex-2-enes in 70-95% yields after 0.05-0.10 F/mol of electricity has been passed.

In contrast to a literature report, diazomethane and diazoacetic ester add to the CC double bond of tetracyanoethylene and ethylenetetracarboxylic ester.The behavior of the 1- and 2-pyrazolines deviates from the rule.
