Wagner-Meerwein-Type Rearrangements of Germapolysilanes - A Stable Ion Study

(Chemical Equation Presented). The rearrangement of tris(trimethylsilyl)silyltrimethylgermane 1 to give tetrakis(trimethylsilyl)germane 2 was investigated as a typical example for Lewis acid catalyzed Wagner-Meerwein-type rearrangements of polysilanes and polygermasilanes. Direct 29Si NMR spectroscopic evidence is provided for several cationic intermediates during the reaction. The identity of these species was verified by independent synthesis and NMR characterization, and their transformation was followed by NMR spectroscopy.

Anionic Cadmium Complexes Containing the Bulky Tris(trimethylsilyl)germyl and Tris(trimethylsilyl)silyl Ligands

The first triiodo-bridged tris(trimethylsilyl)silyl- and tris(trimethylsilyl)germyldicadmium anionic complexes were prepared from CdI2 and 2 equiv of LiE(SiMe3)3 (E = Si and Ge) in hexane. The crystal structure of the germyl derivative 1 was determined. It crystallizes as a lithium salt from pentane in the Cmcm space group (orthorhombic) with a = 14.494(2), b = 16.334(3), and c = 27.361 ?, V = 6478 ?3, and Z = 4. The complex anion of 1, [(Me3Si)3GeCd(μ-I3)CdGe(SiMe 3)3-], exhibits two approximately tetrahedrally coordinated cadmiums with three iodides in trigonal bridging positions between the cadmiums. Efforts to prepare similar chloride-bridged structures were not fruitful.
