  Reactivity of AlMe3 with titanium(IV) Schiff base complexes: X-ray structure of [Ti{(μ-Br)(AlMe2)}{(μ-Br)(AlMe2X)}(salen)] · C7H8 (X=Me or Br) and reactivity studies of mono-alkylated [Ti(Me)X(L)] complexes

  摘要：

  [TiCl2(salen)] (1) reacts with AlMe3 (1:2) to give the heterometallic Ti(III) and Ti(IV) complexes [Ti{(mu-Cl)(AlMe2)}{(mu-Cl)(AlMe2X)}(salen)] (X = Me or Cl) (2) and [TiMe{(mu-Cl)(AlCl2Me)}(salen)] (3). Addition of diethyl ether to 3 affords [Ti(Me)Cl(salen)] (4). The analogous reaction of [TiBr2(salen)] (5) gives the crystallographically characterised [Ti{(mu-Br)(AlMe2)}{(mu-Br)(AlMe2X)}(salen)] (X = Me or Br) (6) and [Ti(Me)Br(salen)] (7) in a single step, whilst the comparable reaction of [TiCl2{(3-MeO)(2)salen}] (8) with AlMe3 yields [Ti(Me)Cl{(3-MeO)(2)salen}] (9) with no evidence of titanium(III) species. Reactivity of both halide and methyl groups of 4 has been probed using magnesium reduction, SbCl5 and AgBF4 halide abstraction and SO2 insertion reactions. Hydrolysis of [Ti(Me)X(L)] complexes affords mu-oxo species [TiX(L)](2)(mu-O) [X = Cl, L = salen (13); X = Br, L = salen (14); X = Cl, L = (3-MeO)(2)salen (15)]. (C) 1999 Elsevier Science S.A.

  摘要：

  钛（IV）Schiff碱配合物的合成已使用四齿赛伦配体及其衍生物[L = salenH 2  =  N，N'-双（水杨基）乙二胺]进行了研究。已经观察到[TiX 2（L）]，[（thf ）TiX 2（L）]和[TiX 4（LH 2）]形式的络合物，这些产物的性质取决于salen衍生物，卤化物和反应使用的条件。[（thf ）2 TiF 4 ]与salenH 2的反应生成了络合物[TiF 4（salenH 2）] 1甚至在甲苯回流后也不能消除HF形成[TiF 2（salen）] 2。使用thf中的甲硅烷基化的席夫碱salen（TMS）2（TMS = Me 3 Si）和[（thf ）2 TiF 4 ]，可以90％的收率获得化合物2 。化合物2已经通过单晶X射线衍射表征。将salenH 2和TiCl 4等摩尔比回流，得到先前制备的[TiCl 2（salen）] 3，同时在室温下搅拌相同的反应物，得到七配位溶剂加合物[（thf

  Attempts to prepare [TiO(salen)] (H(2)salen = 1,2-HOC6H4CH=NCH2CH2N=CHC6H4OH-1,2) and its homologues, analogues of the well known complexes related to [VO(salen)] were only partially successful, in that all the products appear to be polymeric rather than mononuclear, and no crystalline materials were obtained. Homologues of [TiCl2(salen)] were similarly difficult to obtain pure, though we determined a crystal structure for [TiCl2(1,2-OC6H4CMe=NCH2CH2N=CMeC6H4O-1,2)]. This has the expected octahedral coordination, though in common with many such materials, there are molecules of solvent, thf and toluene, within the crystal. This complicates characterisation on the basis of microanalysis. (C) 2000 Elsevier Science S.A. All rights reserved.
