Ruthenium(III) chloride-catalyzed acylation of a variety of alcohols, phenols, and thiols was achieved in high yields under mild conditions (room temperature) in the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF(6)]). The ionic liquid and ruthenium catalyst can be recycled at least 10 times. Our system not only solves the basic problem of ruthenium catalyst reuse, but also avoids the use of volatile acetonitrile as solvent.
在离子液体1-丁基-3-甲基咪唑六氟磷酸盐（[bmim][PF(6)]）中，在温和条件（室温）下，氯化钌（III）催化多种醇、酚和硫醇的酰化反应可高产率实现。离子液体和钌催化剂可循环使用至少10次。我们的体系不仅解决了钌催化剂重复使用的基本问题，还避免了使用挥发性乙腈作为溶剂。
