  The novel tridentate diamidoamine ligands [RC(2C5H4N)(CH2NSiMe3)2)2− (R = H, CH3) have been synthesized and coordinated to TiIV giving the pentacoordinate complexes [MX2(RC(2-C5H4N)(CH2NSiMe3)2}] (M = Ti, Zr; X = Cl, Br). The crystal structure analysis of [TiBr2HC(2-C5H4N)(CH2)2}] (M = Ti, Zr; X = Cl, Br). The crystal structure analysis of [TiBr2HC(2-C5H4N)(CH2NSiMe3))] (10b) confirmed the involvement

  Hydrolysis of the tripodal amidotitanium halides H3CC(CH2NSiMe3)3TiX (X = Cl: 1a; Br: 1b) in the presence of Et3N affords the linear μ-oxo-bridged complex [H3CC(CH2NSiMe3)3Ti]2 (μ-O) (3) which was characterized by X-ray crystallography. Treatment of H3CC(CH2NiPr)3TiX (X = Cl: 2a; Br: 2b), obtained in low yields, under the same conditions only leads to decomplexation of the amido ligand. Under conditions

  在Et 3 N存在下水解三脚架碘化H H 3 CC（CH 2 NSiMe 3）3 TiX（X = Cl：1a ; Br：1b）得到线性的μ-氧桥联络合物[H 3 CC（CH通过X射线晶体学表征了2 NSiMe 3）3 Ti] 2（μ-O）（3）。H 3 CC（CH 2 N i Pr）3 TiX的处理（X = Cl：2a ; Br：2b在相同条件下以低收率获得的）只会导致酰胺配体的分解。在非常缓慢地暴露于H 2 O的条件下，可以分离出2a中两个Ti-N键上的水的主要加成产物，其特征为[H 3 CC（CH 2 -i（μ-Cl））2（μ- O）（4），晶体结构分析建立了一个三重桥接的中心Ti（μ-O）（μ-Cl）2 Ti单元，用两个摩尔当量的n BuLi进行质子化并随后除去LiCl，得到了μ-oxo络合物[H 3 CC（CH 2 N i Pr）3 Ti] 2（μ-O）（5）。

• Tripodal amido-titanium and -zirconium complexes containing a trisilylsilane-derived ligand framework

  A series of amido-titanium and -zirconium complexes containing a tripodal amide with a trisilylsilane ligand framework has been prepared. The primary isolable products in the reaction of SiMe (SiMe(2)NHR)(3) (R = 4-MeC(6)H(4), 2-FC6H4 or 4-MeOC(6)H(4)) with LiBu(n) and ZrCl4 in diethyl ether are the [Li(OEt(2))(2)Cl] adducts of which the five-co-ordinate complex [(4-MeOC(6)H(4)NSiMe(2))(3)MeSi}Zr(mu Cl)(2)Li(OEt(2))(2)] and the six-co-ordinate [(2-FC(6)H(4)NSiMe(2))(3)MeSi}Zr(mu-Cl)(2)Li(OEt(2))(2)] have been characterised by X-ray crystallography. In the latter one of the fluorine atoms of the peripheral 2-FC6H4 groups is weakly coordinated to the metal. Stirring of the (Et(2)O)(2)LiCl adducts in toluene generates the four-co-ordinate complexes [ZrSiMe(SiMe(2)NR)(3)}Cl]. Upon reaction of [MSiMe[SiMe(2)N(C6H4F-2)](3)}Cl] (M = Ti or Zr) with AgO3SCF3 the corresponding triflates were obtained which are sufficiently stable to be isolated, The halide ligand may be readily substituted to give the corresponding methyl, ethynyl and cyclopentadienyl complexes.
