摘　　要：以邻苯二胺、乙酸和碘甲烷为原料合成了1,2-二甲基苯并咪唑,以此为基础与1-溴代烷和HBF4反应得到苯并咪唑溴盐和苯并咪唑四氟硼酸盐两个系列离子液体。产物结构经1HNMR和IR确证。并对苯并咪唑四氟硼酸盐离子液体的催化性能进行了初步研究。Two series of ionic liquids benzimidazolium bromide and tetrafluoroborates were synthesized via the reaction of 1-bromoalkane and HBF4 upon 1,2-dimethyl benzimidazole, which was prepared using o-phenylenediamine, acetic acid and methyl iodide as the starting materials. The structures of the target compounds were confirmed by ^1HNMR and IR spectrometry. The catalytic properties of benzimidazolium tetrafluoroborates were preliminarily studied.
