中文摘要	a series of cobalt(ii) complexes containing tridentate 2-pyrazolyl-substituted 1,10-phenanthroline ligands (l) with the general formula [lcocl2] have been successfully synthesized and fully identified by ir spectroscopy, elemental analysis and mass spectroscopy. cobalt complexes co4co8 were further confirmed by x-ray crystallographic analysis, and all the complexes adopted distorted trigonal pyramid geometries around the cobalt center. in combination with methylaluminoxane, the complexes exhibit high cis-1,4-selectivity for 1,3-butadiene polymerization. the catalytic activities of the complexes mainly depend on the nature of the substituent and its position at the pyrazolyl ring of the ligand. complexes having a bulkier substituent on the pyrazolyl ring of the ligand show lower catalytic activity and the incorporation of electron-withdrawing substituent enhances the activity. polymerization behaviors were almost not affected with varying [al]/[co] ratio, but both activity and the cis-1,4 content decrease slightly as polymerization temperature increasing. copyright (c) 2013 john wiley & sons, ltd.
