【摘要】 以碱性离子液体[bmim]OH作为催化剂,在无溶剂条件下,催化Knoevenagel反应和Perkin反应两类缩合反应.实验结果表明,该离子液体对Knoevenagel反应具有很高的催化活性,一系列的芳香醛和活泼亚甲基化合物在室温条件下10～30min内顺利完成反应,以85%～95%的高产率生成取代烯烃产物.离子液体经简单处理后能多次循环使用.此外,初步探讨了该碱性离子液体在Perkin反应中的应用.更多还原

【Abstract】 Basic ionic liquid [bmim]OH has been introduced as catalyst and reaction medium for Knoeve-nagel and Perkin reactions. The Knoevenagel condensation proceeded efficiently in [bmim]OH at room temperature in 85%～95% yields within 10 to 30 min. The ionic liquid could be reused conveniently. Moreover, [bmim]OH has been preliminarily investigated in Perkin reaction.更多还原
