A 1,2-dibromodigermene having Bbt groups (Bbt = 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl) was synthesized by the reaction of BbtLi with GeBr2-dioxane. X-ray crystallographic analysis revealed that it retains the Ge=Ge double bond in the solid state, while the equilibrium between the 1,2-dibromodigermene and the corresponding bromogermylenes in solution was evidenced by the UV-vis spectroscopic studies and the chemical reactions. The reactions of the 1,2-dibromodigermene with elemental sulfur in toluene resulted in the formation of a cis-dithiadigermetane derivative, indicating the generation of a transient germathiocarbonyl bromide derivative via the sulfurization reaction of the Bbt-substituted bromogermylene generated in the equilibrium state.
