Product 1

HCID 2072571-Ethyl-N,N,N',N',N'',N''-hexamethylsilanetriamineYield 85%

Conditions

Temperature: 240 °C

Procedure

The reaction was carried out as in Example 3; however, the acetylene pressure was increased to 150 psig and the reaction temperature was maintained at 240° C. Vinyltris(dimethylamino)silane was the single major product at a yield of 85% theoretical. Ethyltris(dimethylamino)silane and 1,2-bis(trisdimethylamino)silylethane were also formed, each in approximately a 2 to 3% yield. Vinyltris(dimethylamino)silane was also formed in approximately 10% yield.
