  Diverse Pathways of Activation and Deactivation of Half-Sandwich Aryloxide Titanium Polymerization Catalysts

  摘要：

  A series of half-sandwich aryloxide titanium complexes, [CpTi(OAr)Me-2] (CP = C5H5; OAr = OC6H3-Me-2-2,6, OC6H3Et2-2,6, (OC6H3Pr2)-Pr-i-2,6, (OC6H3Pr2)-Pr-t-2,6, and OC6HPh4-2,3,5,6), have been synthesized. These compounds react with B(C6F5)(3) to give thermally unstable complexes [CpTi(OAr)Me][MeB(C6F5)(3)]. Two different deactivation pathways have been identified within the series. The tetraphenylphenoxide, cationic methyl compound decomposes cleanly at room temperature to give [CpTi(OC6HPh4-2,3,5,6)(C6F5){CH2B(C6F5)(2)}] and methane with a first-order rate constant of 7.6(2) x 10(-4) s(-1) at 25 degrees C. For relatively smaller aryloxide ligands, OAr = (OC6H3Pr2)-Pr-i-2,6, (OC6H3Bu2)-Bu-t-2,6, a Me/C6F5 exchange takes place, yielding CpTi(OAr)Me(C6F5) and MeB(C6F5)(2). The cationic titanium complexes are shown to be active for the polymerization of 1-hexene. At -20 and 0 degrees C, first-order dependence on the concentration of 1-hexene is observed. The rate of polymerization decreases with increasing steric hindrance of aryloxides except for OAr = OC6HPh4-2,3,5,6.

  Preparation of Novel Titanium Complexes Bearing o-Phosphinophenol Ligands

  摘要：

  The preparation of novel titanium complexes bearing o-phosphinophenol ligands is reported. The feature of this ligand system is that its electronic and steric properties can be independently tuned. The complexes were found to be fluxional by H-1 NMR analysis at low temperature. An X-ray structural analysis showed that in the solid state the molecule is chiral at the metal center. These complexes were shown to be effective catalysts for olefin hydrogenation and imine hydrosilylation.
