    Project supported by the Natural Science Foundation of Jiangsu Province (No. BK20150282) and the Scientific Research Foundation of Suzhou University of Science and Technology (No. XKQ201417).

A new magnetic nanoparticle supported palladium catalyst was successfully prepared by attaching palladium acetates to imino-pyridine ligand functionalized silica-coated nano-Fe3O4. The as-prepared catalyst was characterized by element analysis, FTIR, TEM, XPS and ICP-AES. It was found to be an efficient catalyst for Suzuki reactions in aqueous medium. And the reactions of various aryl bromides with arylboronic acids could be carried out under air and low Pd loading conditions with 83%~98% yields. Moreover, the catalyst could be easily recovered by magnetic separation and reused five times without a significant loss of catalytic activity.
