The reaction of [tris(trimethylsilyl)methyl]tribromogermane with magnesium in the presence of olefins and acetylenes has been investigated. 1,4-Digermabicyclo[2.2.0]hexanes and bromogermacyclopent-3-ene are obtained in the reactions of [tris(trimethylsilyl)methyl]bromogermylene with olefins and 1,3-butadiene, respectively. In the presence of diphenylacetylene a 1,2-dihydro-1,2-digermacyclobutene was
