Abstract By hydrosilylation of triethoxyvinylsilane (1), 1, 5-hexadiene (10) and 3, 3-dimethyl- 3-sila-1, 4-pentadiene (14) with triethoxysilane (2) we obtained 1, 2-bis (triethoxysilyl) ethane (3), 1, 6-bis (triethoxysilyl) hexane (11) and 1, 5-bis (triethoxysilyl)-3, 3-dimethyl-3- silapentane (15). The reaction of 3 with triethanolamine (4), triisopropanolamine (6) and tris (1-t-butyl-ethanol) amine (8) leads to the 1, 2-disilatranylethanes 5, 7 and 9. The 1, 6- ...
