methylchlorotrisilanes SiClMe2–SiClMe–SiClMe2 and SiCl2Me–SiClMe–SiCl2Me the stepwise reaction with first HC(OMe)3/[AlCl3] and second HNEt2 leads to the formation of (diethylamino)(methoxy)-methylchlorooligosilanes. The products were investigated by means of 29Si, 1H NMR spectroscopy and GC/MS measurements.

Trialkyl orthoformates in the presence of aluminiumchloride represent quite useful reagents to generate silicon alkoxides from chlorosilanes. 3-Cyanopropyltrichlorosilane and 2-[(2-trichlorosily)ethyl]-pyridine give the triethoxy compounds 3-cyanopropyltriethoxysilane and 2-[(2-triethoxysilyl)ethyl]-pyridine respectively. Via this route, in methylchlorooligosilanes a partial or complete exchange of

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
Trisilanes bearing hydrogen atoms at two more silicon atoms reacted with a zero-valent platinum complex [Pt(dppe)(η2-C2H4)] to give various types of mononuclear and dinuclear platinum–silyl complex...
