摘　　要：两个单桥连的双环戊二烯(C_5Me_4H)E(C_5Me_4H)(E=C_6H_4,(C_6H_4)_2)分别与Re_2(CO)_(10)在均三甲苯中加热回流,得到了2个双核配合物(E)[(η~5-C_5Me_4)Re(CO)_3]_2(E=C_6H_4(1),(C_6H_4)_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。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.
