derivative with n-BuLi, 3-fluorocyclopropene derivative was formed, which underwent Diels-Alder reaction with DPIBF to give an endo-endo adduct. Additionally, fused tricyclic 3,3-difluorocyclopropane and cis-1-chloro-3-fluorocyclopropane derivatives were underwent ring-opening reaction of cyclopropane by BF3●Et2O, respectively, and 1,4-diphenylnaphthalene derivatives were obtained.
