Procedure

The reaction was carried out as in Comparative Example 5, except that triethoxysilane was used as the starting silane. The reaction as monitored by GPC and was complete in two hours. Vinyltriethoxysilane (79%) was the major product formed and significant amounts of 1,2-bis(triethoxysilyl)ethane (13%) and tetraethoxysilane (8%) by-products, were also formed.
