چکیده

A new catalyst of palladium containing guanidine as stabilizer ligand grafted on functionalized MCM-41 (Pd(0)-guanidine@ MCM-41) was prepared during post-grafting procedure and characterized by SEM, EDS, WDX, BET, TEM, TGA, ICP and FT-IR techniques. Further this catalyst was used as efcient and recyclable nanocatalyst for the carbon–carbon cross-coupling reactions such as Suzuki and Stille reactions. Biphenyls were synthesized in short reaction times and high yields in the presence of this catalyst. This catalyst was reused up to 10 times in Suzuki reaction that shows high recyclability of this catalyst
