Novel multifunctional ionic liquids (ILs) are generated by addition of HBr or HCl to alkylammonium nitrates ([RNH3(+)] [NO3(-)]) and to 3-methyl-1-(butyl-4-sulfonyl)imidazolium nitrate ([BMIM(SO3H)][NO3]). The resulting [RNH3(+)] [NO3(-)]/HX and mono (3-methyl-1-(butyl-4-sulfonyl)imidazolium) monohalogenide mononitrate ([BMIM(SO3H)][NO3)x(X)y] (X = Br, Cl)) systems act as solvent and promoter for aerobic oxidative halogenation of arenes under mild conditions in high yields that can be repeated over several cycles.
新型多功能离子液体（ILs）是通过向烷基铵硝酸盐（[RNH3(+)] [NO3(-)]) 和 3-甲基-1-(丁基-4-磺酰基)咪唑鎓硝酸盐 ([BMIM(SO3H)][NO3]) 中加入 HBr 或 HCl 而生成的。所得到的 [RNH3(+)] [NO3(-)]/HX 和单（3-甲基-1-(丁基-4-磺酰基)咪唑鎓）单卤化物单硝酸盐 ([BMIM(SO3H)][NO3)x(X)y] (X = Br, Cl)) 体系在温和条件下作为溶剂和促进剂，用于芳族化合物的有氧氧化卤化，产率高，可重复进行几个循环。
