| 英文摘要 | The intermediates formed upon activation of 8-mesitylimino-5,6,7-trihydroquinolylnickel dichloride [LNiCl2] with AlR2Cl (R = Me, Et) have been studied by H-1 NMR and EPR spectroscopy. Activation of LNiCl2 with AlEt2Cl has been shown to afford diamagnetic ion pair [(LNiEt)-Et-II][AlEt3Cl](-), whereas the use of AlMe2Cl as activator yields the paramagnetic ion pair with proposed structure [LNiII(mu-R)(2)AlMeCl](+)[AlMe3Cl](-) (R = Cl or Me). With time, both ion pairs convert to bis-ligated Ni(I) complexes with proposed structures [L2NiI](+)[A](-), where [A](-) = AlEt3Cl- or AlMe3Cl-, respectively. Ethylene reactivity examination reveals that ion pairs [(LNiEt)-Et-II]+[AlEt3Cl](-) and [LNiII(mu-R)(AlMeCl)-Al-2](+)[AlMe3Cl](-) are the closest precursors of the active species of polymerization. |
