A series of 2-bromo-4-phenyl-endo-tricyclo [3.2.1.02,4]-oct-6-ene,and substituted 2-chloro-3,3-diflouro-4-phenyl-endo-tricyclo [3.2.1.02,4]-oct-6-ene were prepared by Diels-Alder reaction of 1-Aryl-2-bromocyclopropene, substituted 1-Aryl-2-chloro-3,3-Cyclopropeneand and cyclopentadiene. The character of cyclopropene which have high ring strain and high σ、π electron density. It can react with cyclopentadiene to get cyclo-produce. In this study, the same character of steric effect and endo rule in Diels-Alder Reaction.
