Stannyloligosilanes 1 and 2 with terminal organotin groups are available by reacting alkali metal tri-or diorganostannides with α,ω-dichloro-or difluorosilanes, or by treatment of organochlorostannanes with α,ω-difluorosilanes in the presence of magnesium. Attempts to functionalize the triorganotin derivatives 2 by halogenation reagents did not result in the halogen compounds 5; instead cleavage of silicon-tin bonds is observed. In contrast, reactions of the hydridotin derivatives 1 with CHX3 (X = Cl, Br) lead to the quantitative formation of the bis(chloro-or bromostannyl)oligosilanes 5. All compounds were characterized by NMR, IR, MS and elemental analysis. In addition, the triorganotin compound 2i and the hydridotin species 1b have been characterized by X-ray crystallography.

Stannylsilanes were synthesized in high yields by reaction of organotinchlorides with organofluorosilanes and magnesium. The fluorosilanes were prepared in good yields and under mild conditions by reaction of the corresponding chlorosilanes with [n-Bu4N][Ph3SnF2]. All products were characterized by 29Si, 119Sn NMR spectroscopy and elemental analysis.
