离子液体,即[甜菜碱][H 2 PO 4 ],被发现是无溶剂条件下xanthen-9-ol与不同亲核试剂直接取代反应的有效催化剂。该催化体系易于操作,后续后处理程序简单,离子液体催化剂可在高催化活性水平下重复使用至少五个循环。此外,离子液体制备简单,原料廉价,生物相容性好。因此,我们的研究提出了一种有趣且可持续的直接替代酒精的方案。

An ionicliquid, namely [Betaine][H2PO4], was found to be an efficientcatalyst for the direct substitution reaction of xanthen-9-ol with different nucleophiles under solvent-free conditions. This catalytic system is easy to be operated and the following work-up procedure is simple, with the ionicliquidcatalystreusable for at least five cycles at a high catalytic activity level. In addition, the
