Ethylene oligomerizations by -N=N- bridged Ni(II) catalysts derived from pyrazole-scaffold based binucleating ligands having alkyl and aryl pendent arms |
| 초록 |
The coordination and organometallic chemistry of a series of diazine (N2) bridged Ni(II) catalysts derived from pyrazole-scaffold based ligands bearing alkyl and aryl pendent arms is depicted. Binucleating ligands have been obtained as condensation products between 3,5-dichloroformyl-1H-pyrazole and aliphatic/aromatic primary/secondary amines at anhydrous conditions. The Ni(II) catalysts were activated with ethyl aluminum sesquichloride (EASC) to oligomerize the ethylene mainly into C4, C6, C8 and C10 fractions with activities up to 1.4 and 0.93 X 106 g/mol atm 0.5 h, at 30 and 50 oC, respectively. All catalysts are found to be electrochemically active in the working potential range of -2 to +2 V. Change in the potential of Ni(II) is provoked by the N4 donor bridging ligands which pressurizes the ethylene oligomerization activity |
