Conditions

Temperature: 40 °C

Procedure

In an inert atmosphere enclosure, into a 200 Ml glass ampoule equipped with a Teflon/glass valve and magnetic stirring bar were added platinum acetylacetonate (0.04 g, 0.1 mmol) and n-octyltriallylsilane (20.0 g, 75.6 mmol). Subsequently, trichlorosilane (87.17 g, 643.5 mmol) was distilled into the ampoule using a vacuum line transfer system. The ampoule was placed in an oil bath and heated slowly to 40° C., at which temperature it was kept for 12 days. The excess trichlorosilane was removed in vacuo, and distillation of the product yielded 37.6 g (74.1% yield), b.p. 202°-20° C. at 0.001 mm Hg of n-octyl-tris-[3-(trichlorosilyl)propyl]silane.
