A new Pd-SILP based on amino functionalized imidazolium ionic liquid immobilized on Merrifield resin ([email protected]) has been synthesized. The catalyst was characterized by different techniques like FT-IR, SEM-EDS, TEM, TGA-DTA and XPS. The catalyst has shown to be highly active in Suzuki-Miyaura cross-coupling reaction of various aryl halides and aryl boronic acids in ethanol at room temperature. The activity of catalyst and the nature of product were highly dependent on the type of the solvent used, as well as the substituents present on the aryl halides. The protic polar solvent ethanol gave desired cross-coupling product in good to excellent yields at room temperature. However the aprotic polar solvent THF gave homocoupling product. The catalyst showed at least five times recyclability without a decrease in product yield.

合成了一种基于氨基官能化的咪唑鎓离子液体的新型Pd-SILP，该离子液体固定在Merrifield树脂上（[受电子邮件保护]）。该催化剂用不同的技术表征，如FT-IR，SEM-EDS，TEM，TGA-DTA和XPS。室温下，该催化剂在各种芳基卤化物和芳基硼​​酸在乙醇中的Suzuki-Miyaura交叉偶联反应中显示出很高的活性。催化剂的活性和产物的性质高度取决于所用溶剂的类型以及芳基卤化物上存在的取代基。质子极性溶剂乙醇在室温下以良好至优异的产率提供了所需的交叉偶联产物。然而，非质子极性溶剂THF给出均偶联产物。该催化剂显示出至少五倍的可循环性，而产物收率没有降低。
