Abstract
The benzyliminophosphorane 4-ButC6H4CH2P(Ph)2==NC6H2Me3-2,4,6 reacted with TiCl4 or ZrCl4 to give the N-donor adducts, MCl4{4-ButC6H4CH2P(Ph)2==NC6H2Me3-2,4,6}. Whereas the zirconium compound proved unreactive, solutions of the titanium analogue at 10–20 °C slowly underwent C–H activation to give the phosphoranato complex TiCl3{4-ButC6H4CHP(Ph)2==NC6H2Me3-2,4,6}. The trichloro complexes MCl3{4-ButC6H4CHP(Ph)2==NC6H2Me3-2,4,6} were also accessible from Li[4-ButC6H4CHP(Ph)2==NC6H2Me3-2,4,6] and MCl4 (M = Ti or Zr). The reaction of 4-ButC6H4CH2P(Ph)2==NC6H2Me3-2,4,6 with Zr(NMe2)4 in refluxing toluene led to Zr(NMe2)3{4-ButC6H4CHP(Ph)2==NC6H2Me3-2,4,6}. The compound is fluxional in solution. Treatment with an excess of Me3SiCl led to silylation of the ligand to give ZrCl4{4-ButC6H4CH(SiMe3)P(Ph)2==NC6H2Me3-2,4,6}. The structures of 4-ButC6H4CH2P(Ph)2==NC6H2Me3-2,4,6 and Zr(NMe2)3{4-ButC6H4CHP(Ph)2==NC6H2Me3-2,4,6} were determined by X-ray diffraction.
