Base catalysed hydrogenation of methylbromooligosilanes with trialkylstannanes, identification of the first methylbromohydrogenoligosilanes
摘要:
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.

The Lewis-base catalysed hydrogenation of methylchlorodisilanes with trialkylstannanes is also applicable to higher methylchlorooligosilanes without cleavage of the SiSi bonds. In this way it was possible to prepare methylchlorohydrogentri- and tetrasilanes. Using trisilanes with a SiClMe middle group the first hydrogenation takes place exclusively at this silicon atom under formation of a SiHMe group
A number of differently substituted isotetra- and isoheptasilanes were synthesized.
