An efficient synthetic method for successful synthesis of basic amine denderon on SBA-15 and related Pd(II) complex as a novel catalyst has been developed. This modified mesoporous material was characterized by various techniques such as TEM, XRD, atomic absorption spectroscopy, N-2 adsorption-desorption, and FT-IR. The prepared novel heterogeneous catalyst was evaluated in Heck coupling reaction. The very stable hybrid material catalyst was easily recovered, showed negligible Pd leaching, and retained good activity for at least ten successive runs without any additional activation. The catalytic activities of the prepared catalysts were investigated by employing aerobic oxidation of alcohols and Heck coupling as model reactions. The yields of the products were in the range from 75 to 92 %. The catalyst can be readily recovered and reused at least five consecutive cycles without significant leaching and loss its catalytic activity.
