Palladium complex of 2‐(diphenylphosphino)benzaldehyde (P,N‐ligand) was immobilized on three different amino functionalized supports such as MCM‐41, SBA‐16, and Fe 3 O 4 nanoparticles (NPs) to evaluate their catalytic activity toward O‐arylation reaction. Catalytic results showed that P,N−Pd‐MCM‐41 catalyst exhibited much higher activity than the other two catalysts due to the higher active surface sites and could be reused for several runs without significant loss in its catalytic activity. Notably, the reaction was done under solvent‐free condition which is important from the green chemistry point of view. The catalysts were characterized by different techniques including X‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FT‐IR), thermogravimetric analysis (TGA), transmission electron micrograph (TEM), scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy (XPS), energy dispersive X‐ray spectroscopy (EDS), elemental analysis (CHN), inductively coupled plasma (ICP) spectroscopy, and N 2 adsorption–desorption analysis.
