Trapping of the Dichlorocarbene Intermediate in the Reactionof α-Cyanobenzyl carbanion with Carbon Tetrachloride

Department of Chemistry, Nankai University, Tianjin 300071

Received Date: 29 February 1996

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,l-dichloro-2,3-dicyano-2,3-diphenylcyclopropane.
- dichlorocarbene,
- S_N2 vs. ET mechanism,
- CCl₄
