Highly efficient recyclable heterogeneous palladium catalyst for C–C coupling, amination and cyanation reactions

An inexpensive, air–moisture stable and reusable PS–Pd(II)–anthra complex was synthesized by reacting chloro-methylated polystyrene with anthranilic acid to get polymer anchored ligand which was then reacted with PdCl2 to get polymer anchored complex. This complex was characterized by different spectroscopic and elemental analyses. The activity of the Pd-complex as catalyst was tested for the Suzuki, Heck, Sonogashira cross-coupling and also for...
