The design, synthesis and characterization of polynuclear materials for applications for catalysis

The synthesis and characterization of new chitosan- and 6-deoxy-6-amino chitosan-supported ligands is discussed. This was achieved via the reaction of either 2-pyridinecarboxaldehyde or 2-(diphenylphosphino)benzaldehyde with the accessible amino groups of chitosan to afford chitosan-supported Schiff base ligands (2.1-2.4) bearing iminopyridyl and iminophosphine functionalities on the surface. Complexation reactions with [PdCl2(COD)] and [RhCl(CO)2]2 gave the corresponding chitosan-supported complexes (2.5-2.8) and (2.13-2.14). These metal-containing materials and their precursors were isolated as air and moisture stable solids which proved insoluble in common organic solvents and have been characterized analytically and spectroscopically...
