几种无机盐与离子液体催化苊的偶联反应

为合成新型功能高分子中间体，分别研究了在AlCl3，FeCl3，ZnCl2等无机盐和[Bmim]Cl／FeCl3离子液体催化作用下，苊在温和条件常温常压下的偶联反应．经GC／MS分析发现生成了3，3＇-联苊．用GC法考察了不同反应条件对3，3’-联苊产率的影响，得到了各催化剂作用的优化反应条件．结果表明，上述几种催化剂中，[Bmim]Cl／FeCl3离子液体对苊的偶联反应催化效果最好，在该催化剂作用的优化反应条件下，3，3’-联苊产率为48．71％，选择性78．56％，且[Bmim]Cl／FeCl3离子液体对环境无污染，并可循环使用．通过重结晶、层析等方法得到了功能高分子中间体3，3‘-联苊纯品，并用GC／MS，FTIR和^1H NMR等分析测试手段鉴定了其结构．

Coupling reaction of acenaphthene catalyzed by inorganic salts and ionic liquids

To obtain new functional aromatic polymer intermediates,the coupling reaction of acenaphthene catalyzed by inorganic salts,such as AlCl3,FeCl3,ZnCl2 and ionic liquid([Bmim]Cl /FeCl3),was investigated at room temperature and ambient atmosphere.The 3,3'biacenaphthene was determined by GC/MS analysis and the effects of various reaction conditions were studied by GC analysis.The results showed that [Bmim]Cl /FeCl3 was the optimum catalyst,and under the optimum synthesis condition,the yield of 3,3'biacenaphthene is 48.7% and selectivity is 78.56%.Furthermore,[Bmim]Cl /FeCl3 is environmentally benign,and can be reused at least 6 times without loss of any activity.3,3'biacenaphthenys,which may be used as an intermediate of function aromatic polymer materials,was prepared by recrystalling and chromatography the reaction mixture.The structure of 3,3'biacenaphthene was identified by GC,GC/MS,FTIR and 1H NMR analyses.
