Abstract: | Reactions of phosph(V)azane derivatives of bis(anilino)phosphine oxide (PhNH)2P(O)H (1) with AlCl3 and SiCl4 produce two new phosph(V)azane complexes, AlCl(NPh)2P(O)H] (2) and SiCl2(NPh)2P(O)H] (3). In these reactions, an HCl elimination occurs and M─N bonds (M = Si, Al) form directly between a bis(anilino)phosphine oxide ligand with aluminum and silicon halides. The reactions do not require any base to deprotonate the phosphazane ligand. The final products have been fully characterized by means of elemental analysis and IR, MS, and multinuclear NMR (1H, 13C, 31P, 27Al, and 29Si) spectroscopy. |
