Four different ionic liquids, BF4, BF and PF6 were investigated, arid PF6 showed the best effect when used as the reaction media, giving the highest yield in the shortest reaction time. Promoted by KF in PF6, N-aryl or N-alkyl monosubstituted sulfonamides could react with various activated halides and unactivated primary halides smoothly. Reactions were performed at 85℃ for 2~10 hours, and thirteen N-alkylation products were obtained with 70%~97% yields. Moreover, the ionic liquid recovered could be reused for three times with no appreciable decrease in yield and reaction rate.

结果表明，以PF6为反应介质时显示出了最好的效果，反应的时间最短，收率最高。N-芳基或N-烷基单取代的磺酰胺和各类不同结构的活化的卤代烃和未活化的一级卤代烃在PF6中KF作用下，85℃反应2~10h，以70%~97%的优良收率得到了13个N-烷基化产物，而且离子液体回收使用3次后效果未降低。
