Versuchsvorschrift

The reaction was carried out as in Comparative Example 5 except that the starting silane used was triisopropoxysilane, a secondary alkoxysilane, and the reaction temperature was maintained at 140° C. After three hours the reaction was complete as monitored by GPC. The major product formed was vinyltriisopropoxysilane (95%). 1,2-bis(triisopropoxysilyl)ethane (3%) and tetraisopropoxysilane (2%) by-products were also formed.
