Preparation of recoverable Fe3O4/PPy–PdII catalysts for carbonylative cross-coupling reactions

• The preparation method meets the ideas of simpleness, fast and efficiency.
• The catalyst was easily recovered.
• The catalyst revealed high efficiency and high stability during recycling stages.

The hierarchical porous Fe3O4/PPy–PdII catalyst has been synthesized using Fe3O4 microspheres both as chemical template and oxidant source under sonication. The catalyst characterized by TEM, XRD, FT-IR, XPS and vibrating sample magnetometry (VSM). The catalyst showed high reactivity for the carbonylative cross-coupling reaction of aryl iodides with arylboronic acids. This newly developed catalyst could be easily recovered and revealed high efficiency and high stability under the reaction conditions and during recycling stages.
