TiCl4(thf)2 to give the mono-ligand complexes 5–7. The solid state structures of compounds 4–6 have been determined. Complexes 5–7 have been tested for their potential as ethylene oligomerisation/polymerisation systems in conjunction with MAO activator and benchmarked against the Mitsui phenoxy-imine trimerisation system IV. While the phenoxy-amine complex 6 shows a propensity for polymer formation, the phenoxy-imine
已经探索了三井化学乙烯三聚系统(IV)的许多类似物,其中一个供体原子已被修饰。因此,一系列单阴离子三齿苯氧基-亚胺的(3-(吨丁基)-2-(OH)-C 6 H ^ 4 Ç N(C(CH 3)2 CH 2 OME)1,3-(金刚烷基基)-2-(OH)-C 6 H ^ 4 ç N(2' - (2'' - (SME)C 6 H ^ 4)-C 6 H ^ 4)2,3-(吨丁基)-2-( OSiMe 3)-C 6 H 4C N(C(CH 3)2 CH 2 OMe)3)或苯氧胺(3,5-二(叔丁基)-2-(OH)-C 6 H 4 CH 2 -N(2'-(2''-(OMe)C 6 H 4)-C 6 H 4)4)已经制备了配体,并与TiCl 4或TiCl 4(thf)2反应生成单配体配合物5-7。已经确定了化合物4-6的固态结构。已对配合物5-7作为乙烯低聚/聚合系统和MAO活化剂的潜力进行了测试,并相对
