英文摘要The reaction activities for a series of benzylidenequinolin nickel complex systems are studied by density functional theory methods. The effective net charge values obtained on nickel atoms illustrate the correlation with experimental activities. Catalytic activity increases with the higher effective net charge values. The energy gaps (epsilon(1)) between Ni complex's lowest unoccupied molecular orbita (LUMO) and ethylene's highest occupied molecular orbital (HOMO) orbitals are calculated, regarding both pre-catalysts and active species. The results show that there are also relationships between epsilon(1) and catalytic activities. Comparing the pre-catalysts to the active species, the energy gaps epsilon(1) decrease dramatically from about 60 kcal mol(-1) to about 0 kcal mol(-1) for each complex, indicating the important activating role played by the co-catalyst. Finally, it is found that the energy difference values between different spin states relates to catalytic activities for both pre-catalyst and active species as well.
