Vv. Shcherbinin et al., PREPARATION OF TRIBROMOGERMYLCYCLOPROPANES BY INSERTION OF DIBROMOGERMYLENE INTO THE C-BR BONDS OF 1,1-DIBROMO-2-TRIMETHYLSILYLCYCLOPROPANE, Russian chemical bulletin, 46(9), 1997, pp. 1628-1629
The reaction of 1,1-dibromo-2-trimethylsilylcyclopropane with dibromog
ermylene 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 cond
itions, alkyl-substituted gem-dibromocyclopropanes give only alkenyl-g
ermanes resulting from isomerization of the corresponding cyclopropyl-
substituted tribromogermanes.
