Bicyclopropenyls 1-3 have been synthesized by the vacuum gas-phase elimination of beta-halocyclopropylsilane precursors over solid fluoride. Bicycloprop-2-enyl 1 and bicycloprop-1,2'-enyl 2 were isolated and characterized using standard spectroscopic techniques whereas bicycloprop-1-enyl 3 could only be generated in situ and trapped by cyclopentadiene.

3,3'-Bicyclopropenyl (1) was synthesized from a new isomer 3 of 1-chloro-2-(2-chloro-3-trimethylsilylcycloprop-1-yl)-3-trimethylsilylcyclopropanes, which was formed by ene dimerization of 1-chloro-3-trimethylsilylcyclopropene (2) followed by reduction with diimide. Compoumd 2 was generated by debromochlorination of 1-bromo-2,2-dichloro-3-trimethylsilylcyclopropane (4) which was synthesized by dichlorocarbene addition of beta-bromovinyl trimethylsilane.
