    Molecular engineering of coordination pockets in chloro-tris-phenoxo complexes of titanium(IV)
    摘要:
    The chloro-tris-phenoxo complexes [TiCl(OAr)(3)] (OAr = OC6H4CMe-(3)-4 (1). OC6H2Me3-2A (2). OC6H2Me3-2,4,6 (4), OC6H3(CHMe2)(2)-2,6 (5), OC6H3(CMe3)(2)-2,4 (6) and OC6H4Ph-2 (8) are prepared by heating 3 equivalents of the phenol and [TiCl4] in toluene. X-ray crystal structure determinations show that 2 is a phenoxy-bridged dimer with the ortho-methyl groups making the beginning of a pocket about the terminal chloro ligand and 6 is a tetrahedral monomer in which the pocket is more well developed by the ortho-tert-butyl groups. Both 2 and 6 react with dmbipy to give [TiCl(OAr)(3)(dmbipy)] [OAr = OC6H3Me2-2,4 (3) and OC6H3(CMe3)2-2,4 (7)] in which the original pocket is destroyed. Reaction of TiCl4 with 3 equivalents of LiOC6H4Ph-2 in diethyl ether gives [TiCl(OC6H4Ph-2)(3)(diethyl ether)] (9) for which an X-ray crystal structure determination shows a trigonal bipyramidal coordination geometry with the diethyl ether lying trans to the chloro ligand. The three phenoxide ligands make up the equatorial plane which takes the 2-phenyl substituent on each phenoxo ligand away from the chloro ligand resulting in a partially collapsed cavity. The tied-back analogues of 2 and 6, [TiCl{OC6H2Me2-2,4-CH2-6)(3)N)] (11) and [TiCl({OC6H2(CMe3)(2)-2,4-CH2-6}(3)N)] (.) diethyl ether (12), are prepared by adding (HOArCH2)(3)N [Ar = C6HMe2-2,4 and C6H2(CMe3)(2) 2.4] to [TiCl(OCHMe2)(3)] in diethyl ether. An X-ray crystal structure of 12 showed a trigonal bipyramidal structure with a coordination environment about the terminal chloro ligand similar to that found in 6. Complex 12 reacts with pyridine to form the 6-coordinate complex [TiCl{OC6H2(CMe3)(2)-2,4-CH2-6)(3)N)(py)] (13). (c) 2006 Elsevier Ltd. All rights reserved.

    摘要:
    氨基三(酚盐)配体(LTiX,X =氯化物,异丙醇)的钛(IV)配合物与双(三苯基膦)亚胺氯化物(PPNCl)一起是用于二氧化碳和环己烯的开环共聚的活性催化剂体系。它们表现出适度的活性,周转频率值约为60 h-1(0.02 mol%的催化剂,80°C,40 bar的CO2)和高选择性(碳酸盐键> 90%),但它们的绝对性能低于那些最活跃的Ti(IV)催化剂体系。反应随着聚碳酸酯(PCHC)摩尔质量与环氧化物的转化而线性发展,这与受控聚合相一致,并发展出PCHC的双峰摩尔质量分布(最高M n = 42 kg mol-1)。[LTiO i Pr]与氯化四苯基chloridePPh4Cl之间的化学计量反应 可以分离假定的催化中间体[LTi(O i Pr)Cl]-,该中间体使用单晶X射线衍射技术表征。提出了阴离子钛络合物[LTi(OR)Cl]-作为催化循环中醇盐中间体的扩散模型。

    (2) with B(C6F5)3 results in formation of the Lewis acid adduct [Ti(OC6Me2H2CH2)3N][HO.B(C6F5)3] (5). In comparison, treatment of the less sterically encumbered alkoxide Ti(Oi Pr)4 with B(C6F5)3 results in alkoxide-aryl exchange and formation of the organometallic titanium complex [Ti(Oi Pr)3(C6F5)]2 (6). The molecular structures of 3, 4, 5 and 6 have been determined by X-ray diffraction.
