  Hydrierung von Silicium-Halogen-Verbindungen mittels Trialkylstannylchlorid/Natriumhydrid

  摘要：

  Organotinchlorides of the general formula R(3)SnCl and R(2)SnCl(2) (R = Me, n-Bu, Ph) can easily be converted into the corresponding hydrides R(3)SiH and R(2)SiH(2) employing NaH in diethylene glycol dialkyl ethers. Using trialkyltinhydrides like Bu,SnH in combination with a catalyst (tertiary amines, N-heterocycles, phosphonium or ammonium salts), Si-Cl bonds in mono- and disilanes are hydrogenated. In the case of disilanes, Si-Si bond cleavage and concurrent hydrogenation can be afforded with strongly nucleophilic catalysts. Partial hydrogenation is also possible. The whole process can be run cyclically.

  Reaction of 1.1.2.2-tetrachlorodimethyldisilane (4) with 1.4-diazadienes like benzildianil (1), benzildi-p-tolil (2) and benzildi-p-anisil (3) leads to a 1.4-addition product of the disilane under cleavage of the Si-Si bond (1a, 2a, 3a). The structure of 2a was determined by X-ray crystallography (crystal data: monoclinic, P2(1)/n, a = 14.661(4), b = 12.283(2), c = 17.564(5) Angstrom, beta = 103.13 degrees, Z = 4, R = 0.0585 for 5992 independent reflections). Surprisingly, 2a was found to be in the cis-configuration with almost C-2 symmetry and a torsion angle of only 13 degrees. Owing to statistical disorder, some bond lengths are not in the expected range.

  Partial hydrogenation of methylchlorodisilanes and hexachlorodisilane to methylchlorohydrogendisilanes and chlorohydrogendisilanes respectively, is possible by the use of tri-n-butylstannane. Electron-pair donators catalyse the hydrogenation reaction. The Si-29 NMR chemical shifts and coupling constants (1)J(SiH) of some new methylchlorohydrogendisilanes are reported.
