Synthesis and characterization of MCM-41@L-arginine@Pd(0) and its excellent catalytic activity as recyclable heterogeneous catalyst for Suzuki-Miyaura cross-coupling reaction

MCM-41@L-Arg@Pd(0) has been prepared by some consequence reactions. This nano structural material has been characterized via different technique including: XRD, TGA, BET, EDS, X-Ray maps, SEM, ICP-OES and FT-IR analysis. The synthesis of a variety of biphenyl compounds has been achieved successfully via a reaction of aryl halides with arylboronic acids in the presence of this nanostructure (MCM-41@L-Arg@Pd(0)) as green, mild, and versatile catalyst. Mild reaction conditions with excellent conversions of products and simple product isolation procedure are noteworthy advantages of this new methodology and catalyst. Recyclability and reusability of the newly synthesized catalyst make this protocol environmentally benign.
