Abstract
The synthesis of the novel bidentate ligands (HORMeSi)2 [R = Si(SiMe3)3] (2) and (HOR2Si)2SiMe2 [R = SiMe3] (7) as well as the tridentate ligands (HORMeSi)3SiMe (10a) [R = Si(SiMe3)3] and (10b) [R = SiMe(SiMe3)2] is reported. New cyclic metal siloxide complexes were readily prepared from the reaction of 2 and 7 with Ti(OEt)4, Ti(NEt2)4 and Zr(NEt2)4, respectively. The solid-state structures of the novel complexes TiL2 (3) and LTi(OEt)2 (4) [L = (2) - 2H] were determined by X-ray crystallography. Treatment of 10b with CpTiCl3 resulted in the formation of the novel tridentate complex CpTi-(OSiMeR)3SiMe (11).
