Preparation of polystyrene-supported soluble palladacycle catalyst for Heck and Suzuki reactions

A polystyrene-supported palladium complex soluble in tetrahydrofuran and N,N-dimethylacetamide and precipitated in diethyl ether or acetonitrile was prepared from two routes as an excellent and recyclable palladacycle catalyst for carbon–carbon bond formation in Heck and Suzuki reactions to give high yields of the desired products.
