The synthesis, characterization and reactivity of metallacycloalkanes and their precursors

Includes bibliographical references.The synthesis and characterization of a series of new osmium(ll)dibromido complexes of the type [(116-Ar)OsLBr2] (Ar = p-cymene and C6Me6, L = phosphines, phosphites and CO) have been carried out successfully. The complexes were obtained in good yields and characterized by 1 Hand 31 P NMR spectroscopy and elemental analysis. The dibromido complexes were then used in the preparation of osmium bis(alkenyl) and osmacycloalkane complexes

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

Includes abstract.Includes bibliographical references.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..
