Abstract
The syntheses and characterizations of numerous diazasilaphosphetidines and their metal complexes are detailed. Known chemistry was used to synthesize the compounds. NMR spectroscopy (1H, 13C, 31P, and 29Si) and X-ray crystallography were used to identify and characterize the compounds. Treatment of P-chlorodiazasilaphosphetidine with lithium amides produced the P-aminodiazasilaphosphetidines. The P-aminodiazasilaphosphetidines were then oxidized from the phosphorus(III) state to the phosphorus(V) state with cumene hydroperoxide, sulfur, selenium, and p-tolyl azide which produced cyclic heteroallylic compounds. The phosphorus(V) ligands were shown to be excellent chelating ligands to both main group and transition metals. Metal compounds were prepared with aluminum, zinc, thallium, titanium, zirconium, and nickel. It was found that some metals could coordinate one ligand, some two ligands, and some one or two ligands.
