Synthesis of 1, 2, 3-Tricyano-l, 2, 3-Tri (p-chloro-phenyl)Cyclopropane

Chen Si Ying  
The phase transfer catalytic reaction of p-chlorobcnzylcya-nide with carbon tetrachioride in the presence of DMSO have been studied. A new compound, 1, 2, 3-tricyano-1 , 2, 3-tri ( p-chlorophen-yl ) cyclopropane ( Ⅰ ), was obtained. Its structure was identified by elemental analysis, IR, NMR and MS. The reaction mechanism of its formation has been discussed. On the other hand, P, p'-dichloro-α, α'-dicyanostilbene ( Ⅱ ) can be obtained.
