摘　　要：为制备新型功能高分子中间体,研究了在常温常压、Lewis酸FeCl3催化下,苊的偶联反应。通过重结晶、薄层层析等方法得到了目标产物纯品,用1HNMR、FTIR和GC/MS等测试手段鉴定了其结构,表明生成的是3,3′-联苊。用GC考察了不同反应条件对3,3′-联苊产率的影响,当FeCl3和苊的摩尔比为2.3∶1.0,反应时间为5 h,溶剂为CCl4时,3,3′-联苊的产率最高。To obtain new functional .aromatic polymer material, the coupling reaction of acenaphthene catalyzed by FeCl3 was investigated at ambient temperature and atmosphere. Pure 3,3＇-biacenaphthenyls, which may be used as intermediate of functional aromatic polymer material, was prepared by recrystallization and chromatographic methods. The structure of 3,3＇-biacenaphthenyls was identified by 1H NMR,FT IR and GC/MS analysis. The effects of various reaction conditions were studied by GC analysis. The result showed that the optimum synthesis conditions of 3,3＇-biacenaphthenyls were as follows ： the mole ratio of FeCl3 to acenaphthene, 2.3 ： 1.0; the reaction time, 5 h and the solvent of the reaction, CCl4 .
