| Abstract: | The reaction of 1,1-dibromo-2-trimethylsilylcyclopropane with dibromogermylene generated from its dioxane complex made it possible to obtain for the first time the products of insertion of dibromogermylene into one or both C−Br bonds of the dibromocyclopropane. Under similar conditions, alkyl-substitutedgem-dibromocyclopropanes give only alkenylgermanes resulting from isomerization of the corresponding cyclopropyl-substituted tribromogermanes.
