Abstract

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 ...
