Magnetic mesoporous silica composite (MNP@SiO 2 ‐SBA) was obtained via embedding magnetite nanoparticles between SBA‐15 channels. It was silylated with N ‐(3‐(trimethoxysilyl)propyl)picolinamide (TMS‐PCA) and then complexed with Pd(II). The obtained supported Pd(II) catalyst (MNP@SiO 2 ‐SBA‐PCA) was characterized by conventional methods. The prepared magnetic catalyst showed high activity in the Heck and Hiyama reactions under optimal reaction conditions, including solvent, amount of catalyst, base, and temperature. Aryl bromides and iodides showed better results than aryl chlorides, and the catalyst exhibited noticeable stability and reused several times.
