Mn. Elinson et al., ELECTROCHEMICAL TRANSFORMATION OF MALONONITRILE AND ALDEHYDES INTO 3-SUBSTITUTED 1,1,2,2-TETRACYANOCYCLOPROPANES AND BICYCLIC PYRROLINES, Mendeleev communications, (5), 1993, pp. 191-192
Electrolysis of malononitrile in the presence of aldehydes and NaBr in
alcohols in the undivided cell results in the formation of 3-substitu
ted 1,1,2,2-tetracyanocyclopropanes or ialkoxy-1,5-dicyano-3-azabicycl
o[3.1.0]hex-2-enes, depending on the nature of the aldehydes and the q
uantity of electricity passed.
