摘要

The new cascade reaction was found: the formation of cyclopropanes from alkylidenemalononitriles and malononitrile by the only bromine direct action; the action of aqueous bromine on the equal amounts of alkylidenemalononitriles and malononitrile in EtOH–H2O solutions results in the formation of 3-substituted 1, 1, 2, 2- tetracyanocyclopropanes in 55–98% yields.
