A facile way to combine Pd0 with superparamagnetic Fe3O4 nanoparticles (NP) was provided, in which was immobilized directly on the cationic Fe3O4 colloids through electrostatic interaction ( /Fe3O4). Further reduction of the /Fe3O4 NP by vitamin C resulted in Pd0/Fe3O4 NP. These magnetic NP-supported Pd0 clusters showed high efficiency toward Suzuki reactions. After reactions, the Pd0/Fe3O4 NP could be facilely recycled by permanent magnet. This catalyst could be reused for 5 times without significant loss in catalytic activity. Suzuki coupling reaction of a variety of aryl halides was also catalyzed efficiently by this magnetic NP supported Pd0.
