Synthese, Kernresonanzspektren und Schwingungsspektren der Hexamethyltrisilane und Pentamethyltrisilane (XMe2Si)2SiMe2 und (XMe2Si)2SiMeX (XH, F, Cl, Br, I, Ph, OMe)
摘要:
The syntheses, IR, Raman and Si-29 spectra of the title compounds are reported. SiSi force constants, calculated with the aid of normal coordinate analyses, are compared with Si-29 Si-29 coupling constants.

The Lewis base catalysed hydrogenation of methylchlorooligsilanes with trialkylstannanes can also be applied to the hydrogenation of methylbromooligosilanes. In this way methylbromohydrogenoligosilanes were prepared for the first time. Methylbromotrisilanes with an > SiBrMe middle group (e.g. SiBrMe(2)-SiBrMe-SiBrMe(2)) are hydrogenated first at this silicon atom under formation of an > SiHMe group (e.g. SiBrMe(2)-SiHMe-SiBrMe(2)). Brominated silanes containing a quarternary Si(Si)(4) unit (e.g. Si(SiBrMe(2))(4)) do not react with trialkylstannanes.
