| 英文摘要 | The metal atom net charge correlation(MANCC) method was used to study catalytic activities of a series of asymmetric iron complexes bearing 2-imino-1, 10-Phenanthroliyl ligands for ethylene oligomerization. If the catalytic activity is influenced mostly by electronic effect, it has a good correlation to the metal atom net charge. In general, catalytic activities of iron complexes bearing electron-donating alkyl groups increase with the net charges increasing. On the contrary, with the net charges increasing, catalytic activities decrease while the complexes contain electron-withdrawing halogen groups. Based on the above results, we speculated that two different activated centers probably existed in ethylene oligomerization which are [LFe-R](+) and [LFe-R](+2) ([Fe(Cl)RL](+)). When both the electronic and steric effects of coordinative ligand affect the catalytic activity, the charge difference on the two halogen atoms was correlated with it. And it is found that the cataly-tic activity is improved corresponding to the smaller charge difference. |
