We present the use of amine-functionalized silica (NH2-SiO2) as support for palladium nanoparticles (PdNPs) and the use of heterogeneous catalysts (Pd/NH2-SiO2) for the Suzuki, Heck and Sonogashira coupling reactions. The synthesized Pd catalyst is well characterized by XRD, HRTEM, BET, SEM-EDX, FT-IR, and UV-vis spectral techniques. It exhibits efficient catalytic activity for these coupling reactions without the assistance of ligand and copper salts. (c) 2013 Elsevier B.V. All rights reserved.
