以1-甲基咪唑、对二氯苄、对羟基苯甲醛和四氟硼酸钠为原料, 制备了一种含醛基的新型功能化离子液体1-(4-对甲酰基苯氧基亚甲基苄基)-3-甲基咪唑四氟硼酸盐(简写为[fmmim][BF4]). 为拓展功能化离子液体为载体的液相合成反应体系, 以该含醛基功能化离子液体为可溶性液相载体, 进行了Williamson醚化的合成反应, 较高产率和纯度得到了一系列氨基醚类化合物, 切割后得到的目标化合物不需要进行进一步的柱色谱纯化处理, 产率为81%～85%, 纯度为96%～99%. 回收得到的功能化离子液体可以重复套用多次而不影响其功效, 目标化合物的产率在81%～84%之间波动. 结果表明该方法可高效率地用于基于Williamson醚化反应的液相组合化学合成.

The facile and new type aldehyde functionalized ionic liquid 1-[4-(p-formylphenoxy methylene) benzyl]-3-methylimidazolium tetrafluoroborate (abbreviated as [fmmim][BF4]) was prepared via 1-methyl- imidazole, p-xylylene dichloride, p-hydroxybenzaldehyde and sodium tetrafluoroborate as raw materials. In order to develop the use of functionalized ionic liquids in solution phase parallel synthesis, amino-ether compounds were prepared via Williamson etherification using the aldehyde-functionalized ionic liquid as soluble support. The target compounds were obtained in good yields and high purities without column chromatographic purification after cleavage. The yields were 81%～85%, and the purities were 96%～99%. The recovered functionalized ionic liquid could be reused for several times without affecting its activity, and the yields of desired compound was fluctuated between 81%～84%. These results indicated that the presented method could be applied efficiently to the solution-phase combinatorial chemistry based on Williamson etherification.
