| 摘要: 两个单桥连的双环戊二烯（C5Me4H） E（C5Me4H）（E=C6H4，（C6H4）2）分别与Re2（CO）10在均三甲苯中加热回流，得到了2个双核配合物（E）[（η5-C5Me4） Re（CO）3]2（E=C6H4（1），（C6H4）2（2））。通过元素分析、红外光谱、核磁共振氢谱和碳谱对配合物1和2的结构进行了表征，用X射线单晶衍射分析测定了配合物的结构。同时对2个配合物在芳香族化合物Friedel-Crafts酰基化反应中的催化活性进行了研究。 | |

| Abstract: Thermal treatment of two p-phenylene-and p-Biphenylene-bridged biscyclopentadienes (C5Me4H)E(C5Me4H) (E=C6H4, (C6H4)2) with Re2(CO)10 in refluxing mesitylene gave the corresponding complexes (E)[(η5-C5Me4)Re(CO)3]2 (E=C6H4 (1), (C6H4)2 (2)), which were separated by chromatography, and characterized by elemental analysis, IR, 1H NMR and 13C NMR spectroscopy. The molecular structures of complexes 1 and 2 were characterized by X-ray crystal diffraction analysis, showing both them are monobridged biscyclopentadienyl dinuclear rhenium carbonyl complexes. In addition, the catalytic performance of complexes 1 and 2 was also tested, and it was found that both complexes were obviously active for Friedel-Crafts acylation reactions. | |
