摘要：

The reaction of Ga2X4 . 2 dioxane with four equivalents of (Me3Si)(3)SiLi(thf)(3) (= hypersilyllithium) affords for X = Br a 1,3,2,4-disiladigalIetane together with tetrahedral hypersilylgallium(I). For X = Cl an anionic 1,2,3,4-silatrigalletanate, a four-membered heterocycle with a Ga-3 unit, is isolated. These primary examples of gallium/group-14 heterocycles have been investigated by NMR spectroscopy as well as by X-ray single-crystal structure analysis. In addition, the synthesis and structure of bis(hypersilyl) gallium chloride is described. This monomeric molecule has a nearly T-shaped Si2GaCl framework.
