摘要：

The 1:1 mole ratio reaction of t-Bu3In with Sb(SiMe3)(3) results in the formation of the Lewis acid-base adduct t-Bu3In . Sb(SiMe3)(3) (1), while the dimeric compound [t-Bu2InSb(SiMe3)(2)](2) (2) is isolated from the 1:1 reaction of t-Bu2InCl with Sb(SiMe3)(3). Both the 2:1 reactions of t-Bu2InCl with Sb(SiMe3)(3) and t-Bu2InCl with 2 result in the formation of the mixed-bridge compound t-Bu2InSb(SiMe3)(2)In(t-Bu)(2)Cl (3), however, H-1 NMR studies suggest that this compound is unstable in solution. Thermolysis of 1, 2, and t-Bu3Ga . Sb(SiMe3)(3) (4) results in the formation of nanocrystalline InSb or GaSb through a beta-hydride elimination pathway.
