2,2,2′,2′-Tetrabromo-1-phenylbicyclopropyl and 1,1-dibromo-2-(2,2-dibromo-cyclopropyl)methyl-2-phenylcyclopropane have been synthesized, analyzed by X-ray crystallographic techniques, and exposed to acetone-sensitized irradiation. The former compound, whi

Reactions of gem-dibromocyclopropanes of the general structure 1 with methyllithium have been studied.In the most cases cyclopentadienes and/or vinylallenes are the products formed.The results obtained give evidence of a profound substituent effect on the carbene-carbene rearrangement leading to cyclopentadienes.We believe the effect is essentially steric in origin.The results support the mechanism proposed for the rearrangement.
