  Convenient Synthesis of N-Trimethylsilylaminotitanium Trichlorides

  摘要：

  Bis(N-trimethylsilylamino)plumbylenes 1 {[Me3Si(R)N](2)Pb with R = Bu-t (a), Me3Si (b), 9-(9-borabicyclo[3.3.1]nonyl) (c)} react smoothly with an excess of TiCl4 to give PbCl2 and N-trimethylsilylaminotitanium trichlorides 3 a-c. In contrast, the analoguous reaction of the corresponding stannylenes 2a-c leads to mixtures containing unidentified Ti-III compounds, the amides 3a or 3b, bis[bis(trimethylsilyl)amino]titanium dichloride 4b and bis(amino)tin dichlorides 5 a-c. The crystal structure of 3a was determined by X-ray structural analysis. Compound 3a is a dimer in the solid state with distorted trigonal pyramidal surroundings of the titanium atoms. Each titanium atom bears two mu(2)-Cl ligands which are in axial (d(Ti-Cl) = 250.7(1) pm) and equatorial positions (dn(Ti-Cl) = 247.0(1) pm) and two terminal chloro ligands, one in axial (d(Ti-Cl) = 228.0(1) pm) and one in equatorial position (da(Ti-Cl) = 221.1(1) pm). The equatorial Ti-N bonds are short (183.8(2) pm).

  N-Trimethylsilylaminotitanium trichlorides, Me₃Si(R)N-TiCl₃ [R = ^tBu (2a), SiMe₃ (2b), 9-borabicyclo[3.3.1 ]nonyl (9-BBN) (2c)] react with the corresponding plumbylenes 1a - c or with the lithium amides LiN(R)SiMe₃ to give the bis(amino)titanium dichlorides 3a - c, and 4 - 6. The titanium dichlorides 4-6 are the first examples, in which the titanium atom bears two different amino groups. The compounds were characterised by a consistent set of ¹H, ¹³C, ^14/15N and ²⁹Si NMR data.

• Biphenolate Phosphine Complexes of Group 4 Metals

  The preparation and structural characterization of a series of group 4 complexes supported by 2,2'-phenylphosphinobis(4,6-di-tert-butylphenolate) ([OPO](2-)) are described. The reaction of either H-2[OPO] with Ti(OR)(4) (R = Et, Pr-i) or Li-2[OPO] with TiCl4(THF)(2) produced yellowish-orange crystals of Ti[OPO](2), regardless of the stoichiometry of the starting materials employed. Comproportionation of the bis-ligand complex Ti[OPO](2) with 1 equiv of TiCl4(THF)(2) led to the formation of [OPO]TiCl2(THF) as brownish-red crystals. Surprisingly, treatment of H-2[OPO] with [(Me3Si)(2)N](2)MCl2 (M = Zr, Hf), irrespective of the molar ratio, generated colorless crystals of the corresponding bis-ligand complex [OPO](2)M(OH2) as an aqua adduct. The solution and solid-state structures of these group 4 complexes were all characterized by multinuclear NMR spectroscopy and X-ray crystallography, respectively.
