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]₂Ti (3a), [2,6-C₅H₃N(CH₂O)₂]₂Ti (3b), [2,6-C₅H₃N(CPh₂O)₂]TiCl₂ (4) – as well as the closely related N-phenyl derivative PhN(CH₂CH₂O)₂Ti(Cl)Cp (5) have been synthesized. Complexes 2–5 were characterized by ¹H and ¹³C NMR spectroscopy and elemental analysis data. The molecular structure of 3a was determined by X-ray structure analysis.
