摘要：

Dehydrogenative polymerization of pentamethyldisilane by means of Cp2MMe2 (M = Ti, Zr) afforded a mixture of the oligosilanes Me3Si[Me2Si]nSiMe2H; 1,1,2,2-tetramethyldisilane reacts to a mixture of the oligosilanes Me2HSi[Me2Si]nSiHMe2. Dehydrogenative polymerization of 1,2-dimethyldisilane by use of Cp2MR2 (M = Ti, Zr; R = Me, (n)Bu) afforded the new unique cross linked polysilane polymer poly(methylsilane) (MeSiHx)n. The pyrolysis of (MeSiHx)n at 1500-degrees-C (argon) gives a ceramic yield (SiC) of 88%. The polymerization progress is observed and investigated by GLC, GC-MS and Si-29-NMR spectroscopy, and the oligomers. formed at the beginning of the polymerization, are identified,
