Polystyrene Supported [N-(Alanine) Sulfonamide]/Palladium Chloride: Synthesis, Characterization, for Heck Coupling Reactions

para-styrene sulfonyl chloride and (S)-(+)-alanine in the presence of KOH 1 M as a base, and CHCl3 was used as solvent. The formation/presence of monomer was verified using FT-IR and 1H NMR spectroscopy. Polystyrene [N-(alanine) sulfonamide] (PASS) was also prepared from the polymerization of [N-(alanine)] para-styrene sulfonamide (ASS) in the presence of AIBN (azoisobutyronitrile) under atmosphere of nitrogen. Polystyrene [N-(alanine) sulfonamide]/palladium chloride as a polymer-supported palladium complex was also prepared from the reaction of PdCl2(CH3CN)2 with PASS in the presence of KOH 1 M. A green solid was consequently appeared. This catalyst was synthesized for the first time as a polymer-supported palladium and applied in Heck reactions.
