The reaction was carried out in accordance with the procedure of Comparative Example 2, except that the silane used was triethoxysilane and the reaction temperature was 150° C. The reaction was monitored by GPC and was completed in one hour. The major product formed was 1,2-bis(triethoxysilyl)ethane (72%), with vinyltriethoxysilane (25%) and tetraethoxysilane also being formed (3%). With a primary alkyl silane and at lower reaction temperatures, the undesired bis(silyl)ethane was the main reaction product.
