| 英文摘要 | series of ion-pair cobalt contlexes bearing pyridine bisoxazoline ligands were successfully synthesized and characterized by ir spectroscopy and elemental analysis. determined by x-ray crystallographic analysis, complexes 4a, 4b, 4e, and 4f existed as ion pairs comprised of [col2](2+) and [cocl4](2-). in the complex, the cobalt atom was coordinated by six nitrogen atoms from two ligands, and its coordination geometry at the cobalt center of [col2](2+) can be described as distorted octahedron. in combination with ethylaluminum sesquichloride, these cobalt complexes displayed high catalytic activity and cis-1,4-selectivity towards 1,3-butadiene polymerization. the selectivity of the catalytic system can be tuned to predominantly 1,2-fashion via addition of pph3. the effects of reaction parameters and the ligand environment on the polymerization were also investigated.
