摘要：

Amino-di-tert-butylsilanol reacts with tetrabutoxititane in a molar ratio of 2:1 to give di-n-butoxi(bis(di-tert-butyl-n-butoxi)siloxi)titane, (C4H9OSi(CMe3)(2)-O)(2)Ti(OC4H9)(2) (1), and lithium-di-tert-butylchlorositanolate in a molar ratio of 3:1 to give n-butoxi(tris(di-tert-butyl-n-butoxi)siloxi)titane, (HqC40Si(CMe3)2-0)3TiOC41-19 (2). The amino-di-tert-butylsilanol substitutes the four chloroatoms of TiCl4 if the presence of triethylamine as HCl-acceptor. The tetrakis(amino-di-tert-butyl)siloxititane (3) is formed. The lithium salt of di-tert-butylfluorosilanol reacts with TiCl4 in a molar ratio of 2:1 to give 1,1,3,3-tetra-tert-butyl-1-fluoro-3-trichlorotitoxi-1,3-disiloxane, FSi(CMe3)(2)-O-Si(CMe3)(2)-O-TiCl3 (4). In the reaction of di-tert-butyl-chlorosilanol and TiCL4, the anion [chlorosiloxi-octa(tri-mu(2)-chlorotitanate)](-) (5) with protonated di-ethylether as counterion is obtained by using diethylether as HCl-acceptor. The crystal structure determinations of 3 and 5 are reported.
