Abstract: A Pd(II) Schiff base complex as an efficient and highly heterogeneous catalyst was developed by immobilization of a palladium complex on the surface of modified Fe3O4 magnetite nanoparticles. These surface-modified nanoparticles were characterized using various techniques such asSEM, TEM, XRD, FT-IR, EDX and VSM. The palladium catalyst exhibited efficient catalytic activity in Suzuki-Miura coupling reactions. This method has notable advantages such as excellent chemoselectivity, mild reaction conditions, short reaction times and excellent yields. The yields of the products were in the range 75–85%. Also, the nanocatalyst can be easily recovered with a permanent magnet and reused at least five times without noticeable leaching or loss of its catalytic activity. The products obtained from the coupling reaction were first examined by TLC techniques and after confirmation were identified by FT-IR& NMR techniques.
