  A New Class of Mono- and Tetra-nuclear Titanatranes:  Synthesis, Structure, and Ethylene Polymerization Studies. Role of Single-Sited Active Species?

  摘要：

  Mono- and tetranuclear titanatranes bearing the C-3-symmetric aminotriol ligand N(CH2CHPhOH)(3) were synthesized. The structure of the tetratitanium compound was determined by single-crystal X-ray crystallography. The new titanatrane derivative included four aminotriols ligated to four titanium atoms, forming a tetranuclear unit with mu(2)-O and mu(3)-O bridges. The mono- and tetranuclear titanatranes were capable of polymerizing ethylene with a turnover frequency of up to 375 kg of PE/((mol of catalyst) h bar). The polymers obtained had T-m approximate to 133 degreesC, indicative of linear polyethylene, and were further characterized by NMR. The ethylene polymerization activities of mono- and tetranuclear titanium catalysts were related by a factor of 4, indicating possibly the formation of a common single-site active species.
