To solve the recovery and recycling problem of homogeneous palladium catalyst, a cheap and convenient method was developed for the synthesis of magnetic nanoparticles (MNPs) supported palladium catalyst Fe3O4@MOPPA-Pd which is easily in situ separated from the reaction system by the application of a permanent magnet. The catalyst can highly catalyzed the Suzuki reaction and Heck reaction of different halogenobenzenes. Especially, it has higher catalytic activity for Suzuki coupling reaction. Under mild reaction conditions, 300 mmol of bromobenzene reacted with phenylboronic acid catalyzed by 10 mg of Fe3O4@MOPPA-Pd can give the product with 98% yield. And the turnover number (TON) and turnover frequency (TOF) of the catalyst reached 77052 and 51368 h-1, respectively. In addition, Fe3O4@MOPPA-Pd can be easily separated from reaction system in the presence of magnetic field and the catalytic activity was not decreased by at least 4 times recycles.
