Synthesis and Characterization of New Silicon and Titanium Derivatives of Bis(anilino)phosphine Oxide

Abstract

The reactions of bis(anilino)phosphine oxide (C 6 H 5 NH) 2 P(O) H with (C 5 H 5 )2TiCl2 or Me2SiCl2 in a 1:1 molar ratio in THF results in the isolation of new phosph(V)azane complexes (C5H5)2Ti[(N C6H5)2P(O)H] (1) or Cl 2 Si[(N C 6 H 5 )2P(O)H] (2), respectively. In these reactions, HCl or CH4 elimination occurs and N-Ti or N-Si bonds form directly between a bis(anilino)phosphine oxide ligand and organotitanium or organosilicon compounds. The products(1) and (2) have been fully characterized by elemental analysis as well as 1 H, 31 P, 29 Si NMR, and IR spectroscopy.
