A recyclable palladium catalyst supported on magnetic microporous organic polymer (MOP) of 1,1'-bi-2-naphthol (Fe3O4@MOPB-Pd) was synthesized by two steps. After being charactered by transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TG) and vibrating sample magnetometer (VSM), the palladium catalyst was applied in Suzuki coupling reaction in air atmosphere. With 0.01 g of Fe3O4@MOPB-Pd (0.12 mol% Pd based on bromobenzene) as catalyst, 1.0 mmol of bromobenzene reacted with 1.1 equiv. phenylboronic acid at 60 ℃ for 3 h can give the product with 98% yield. In addition, Fe3O4@MOPB-Pd can be easily separated from reaction system in the presence of magnetic field and the 92% yield was achieved even being used at 7th time for the Suzuki coupling reaction of iodobenzene and phenylboronic acid.
