中文摘要fe(iii), cr(iii), fe(ii), co(ii) and ni(ii) chloride complexes supported by 2,6-bis[1-(iminophenyl)ethyl]pyridine have been synthesized and characterized along with single crystal x-ray diffraction. these complexes, in combination with mao, have been examined in butadiene polymerization. the catalytic activity and regioselectivity are strongly controlled by metal center and cocatalyst (mao/co ratio dependent in the case of co(ii) complex). the activity decreases in the order of fe(iii) > co(ii) > cr(iii) approximate to ni (ii) complexes, in consistent with the space around the metal center. polybutadiene with different microstructure content, from high trans-1,4 units (88-95% for iron(iii) and cr(iii)), medium trans-1,4 and cis-1,4 units (55% and 35%, respectively, for iron(ii)) to high cis-1,4 units 79% for co(ii) and 97% for ni(ii) call be easily achieved by varying of the metal center.
