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.
