摘　　要：用苯乙烯及氯仿为原料,在浓碱和相转移催化剂的作用下使氯仿生成二氯卡宾并对双键进行加成得到1,1-二氯-2-苯基环丙烷,粗产率为72.0%。经减压蒸馏后得到无色透明的液体,最终产率可达65.7%,产物结构经IR、1H NMR表征并得到确认。Using styrene and chloroform as raw materials, and 1,1-dichloro-2-phenylcyclopropane can be obtained from the addition reaction between styrene and diehlorocarbene which is formed at the existence of concentrated alkaline and phase transfer catalyst. The crude yield was 72.0%, and after vacuum distil- lation a colorless transparent liquid can be got, the yield was 65.7%. The structure of the product was confirmed by IR and 1H NMR.
