Palladium supported terpyridine modified magnetic nanoparticles as an efficient catalyst for carbon-carbon bond formation

In this paper, a novel catalyst is designed, synthesized and characterized based on the functionalization of magnetic iron oxide nanoparticles by terpyridine as a ligand for the immobilization of palladium. The catalyst is fully characterized by several characterization methods, including SEM, FTIR, DLS, VSM, EDS and XRD analysis. The results of the characterization techniques proved the successful synthesis of the desired catalyst. The applicability of the catalyst was evaluated in Heck and Suzuki reaction. The catalyst showed very good activity through the mentioned carbon-carbon bond formation reactions. The catalyst is magnetically recoverable and could be separated simply from the reaction media by an external magnet. The use of the catalyst in 10 sequential reactions did not show any significant loss in the activity of the catalyst. (C) 2021 Published by Elsevier B.V.
