Abstract

The [N-(2-pyridyl)] para-styrene sulfonamide (PSS) was prepared as a monomer, from the
reaction of para-styrene sulfonyl chloride and 2-amino pyridine in the presence of potassium
hydroxide solution 0.5M as a base, and CH3Cl. Polystyrene [N-(2-pyridyl) sulfonamide] (PPSS)
was synthesized from the polymerization of [N-(2-pyridyl)] para-styrene sulfonamide (PSS). The
Polystyrene bis [N-(2-pyridyl) sulfonamide] palladium (II) as a polymer- supporting palladium
complex was also prepared from the reaction of PdCl2 (CH3CN)2 with PPSS in the presence of
KOH 0.5M. Polystyrene bis [N-(2-pyridyl) sulfonamide] palladium (II) is produced as a novel
heterogeneous catalyst for coupling reactions for C-C bond formation. This method includes
higher yield and has an easier work-up procedure. The structures of the monomer, polymer and
its Pd complex were confirmed by using FT-IR and 1H-NMR spectroscopy. Elemental analysis
of Pd by inductively coupled plasma (ICP) technique and hot filtration test showed loading of the metal into solution from the catalyst The heterogeneous catalyst was recycled without any loss in
its properties.
