A MCM-41-supported palladium (II) α-diimine complex has been synthesized via anchoring of 3-chloropropyltriethoxysilane on mesoporous silica MCM-41, followed by grafting α-diimine ligand through the covalent approach to bind with Pd(II) ion. Different analytical technique such FT-IR, TGA, low angle powder XRD, SEM, TEM, ICP-MS and N₂ sorption were used to characterize the complex. The complex serves as a highly active and recyclable catalyst for Suzuki-Miyaura coupling reaction affording a variety of biaryls with good yields.
