摘要：

A series of 9-aryl-2,3,4,5,6,7-hexahydro-2H-xanthene-1,8-dione derivatives were synthesized from aromatic aldehydes and 1,3-cyclohexanedione derivatives catalyzed by NaHSO4 in ionic liquids, 1-n-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4). The reactions were carried out in boiling water bath for 1 similar to 2 h, and the yield ranged from 1.2% to 93.0%. The catalyst employed is not expensive and the ionic liquid can be reusable. The proposed method is fast, efficient and environmentally friendly.
