In this paper, the preparation of an efficient heterogeneous catalyst system based on the immobilization of Pd nanoparticles on a magnetic nanoparticles core (ImmPd-MNPs) is described. The new catalytic system was characterized by TEM, SEM, XRD, EDX, TGA, FT-IR, VSM and ICP analysis. We have demonstrated that ImmPd-MNPs is an efficient and reusable catalyst for the Suzuki–Miyaura and Sonogashira-Hagihara coupling reactions of various types of aryl iodides and bromides in water as a green and environmentally acceptable solvent. Moreover, the reactions were carried out at room temperature efficiently. The catalyst was easily reused by an external magnet from the reaction mixture and recycled six times without significant loss of activity.
