Convenient and high-yield syntheses for (Ti(cp)(OPh)3) and (Ti(cp)Cl(OPh)2) (cp=η-C5H5) are described.The donor characteristics of the mixed phenoxides (Ti(cp)n(OPh)(4-n)), n=0, 1, or 2, ((TiCl2(OPh)2)2), (Ti(cp)Cl(OPh)2), and of Ti(NMe2)4 have been investigated.Reactions with MCl3 (M=Ti, V, or Cr), VOCl3, MX4 (M=Ti, Zr, Hf, or Sn; X=Cl or Br), and MCl5 (M=Nb, Ta, or Mo) generally feature exchange of OPh and NMe2 groups with halide rather than complexation.In several instances, using appropriate reaction conditions, the solid adducts MX4Ti(NMe2)4 (M=Sn, X=CL or Br; M=Zr or Hf, X=Cl), SnCl4(Ti(cp)2(OPh)2), and ZrCl4Ti(OPh)4 have been isolated and fully characterised by analitycal and spectral data.
