Reaction between 3-But-2-(OSiMe3)C6H3CHN(2,6-R2C6H3)
(where R = H (1a) or Pri
(1b)) and TiCl4(THF)2 affords the octahedral complexes Ti3-But-2-(O)C6H3CHN(2,6-R2C6H3)}Cl3(THF) while in the absence of THF 1b reacts with TiCl4 to give the binuclear complex [Ti3-But-2-(O)C6H3CHN(2,6-Pri2C6H3)}Cl(μ–Cl)3TiCl3]; the complexes give good productivities for ethene polymerisation when activated with MAO.
3-But-2-(OSiMe3)C6H3CHN(2,6-R2C6H3)(当R为H (1a)或Pri (1b)时)与TiCl4(THF)2反应生成八面体配合物Ti3-But-2-(O)C6H3CHN(2,6-R2C6H3)}Cl3(THF),而在无THF的情况下,1b与TiCl4反应生成二核配合物[Ti3-But-2-(O)C6H3CHN(2,6-Pri2C6H3)}Cl(μ–Cl)3TiCl3];这些配合物在与MAO活化时,对
乙烯聚合表现出良好的生产率。
