摘　　要：In Me2SO, an X-philic reaction took place between α-cyanobenzyl carbanion and CCl4. The intermediate dichlorocarbene was trapped by the primary product dicyanostilbene to give the alkene-carbene adduct, 1, 1-dichloro - 2, 3 -dicyano -2, 3 -diphenylcyclopropane.In Me2SO, an X-philic reaction took place between α-cyanobenzyl carbanion and CCl4.
