A simple and efficient method for phosphinefree C–C coupling reactions such as Heck and Suzuki reactions in the presence of pyrrole Schiff base complex of palladium immobilized on mesoporous mesoporous of MCM-41 (Pd-Py-MCM-41) has been reported. The Suzuki reaction was carried out in PEG-400 using phenylboronic acid (PhB(OH)2). Pd-Py-MCM-41 has been found as a promising catalyst for Heck reaction of butyl acrylate with aryl halides (including Cl, Br and I). The catalyst was characterized by FT-IR, TEM, XRD, SEM, BET and ICPOES techniques. The protocol proves to be efficient and environmentally benign in terms of high yield, easy of recovery and reusability of catalyst.
