  摘要：

  Novel titanocanes and spirobititanocanes based on 2,6-bis[hydroxy(diphenyl)methyl]pyridine (1a) and 2,6-di(hydroxymethyl)pyridine (1b) - [2,6-C5H3N(CPh2O)(2)]Ti(O-i-Pr)(2) (2a), [2,6-C5H3N(CPh2O)(2)](2)Ti (3a), [2,6-C5H3N(CH2O)(2)](2)Ti (3b), [2,6-C5H3N(CPh2O)(2)TriCl(2) (4) - as well as the closely related N-phenyl derivative PhN(CH2CH2O)(2)Ti(Cl)Cp (5) have been synthesized. Complexes 2-5 were characterized by H-1 and C-13 NMR spectroscopy and elemental analysis data. The molecular structure of 3a was determined by X-ray structure analysis. (c) 2006 Elsevier B.V.

  Titanium(4+) and zirconium(4+) complexes with pyridinedicarboxylic acid derivatives have been synthesized. The composition and structure of the synthesized 2,6-bis(diphenylhydroxymethyl)pyridine complexes have been corroborated by NMR and IR spectroscopy, and elemental analysis. The complexes activated with methylaluminoxane (MAO) are catalytically active in ethylene polymerization, Depending on the Ti/Al-MAO ratio, the catalytic activity of the complexes varies between 90 and 420 kg PE/mol Ti h atm.
