Palladium Based-Polysaccharide Hydrogels as Catalysts in the Suzuki Cross-Coupling Reaction

A simple PdCl2(TPPTS)2 complex was successfully heterogenized in polysaccharide hydrogel beads by using two different methods: (1) dropping the complex and polysaccharide solution into aqueous or ethanol solution of 0.5 M calcium chloride, and (2) dropping the complex and polysaccharide solution into an aqueous solution of chitosan (C). FTIR analyses of the different beads revealed that the complex was heterogenized via interactions between the...
