摘要：
A palladium-based catalyst supported on novel Fe3O4 @ Poly(ethylene glycol) bridged amine functionalized imidazolium ionic liquid (Fe3O4@PEG-AIm-NH2-IL) was successfully prepared by a facile method. The catalyst was characterized by FT-IR, TEM, VSM, XRD, XPS and TGA-DSC, which showed high activity and stability for the Heck reaction in pure water. Furthermore, the catalyst could be recovered in a facile manner from the reaction mixture and recycled five times without any loss in activity. A novel magnetically separable Fe3O4@PEG-AIm-NH2-IL-Pd was designed and synthesized, which was used as outstanding palladium catalyst for the Heck reaction in pure water. The supported catalyst could be recycled and reused with the simple application of an external magnetic field, while keeping similar catalytic activity for five successive reactions. [GRAPHICS] .
