Abstract
New half-sandwich titanocene complexes (η 5-C 5Me 5)Ti(OC 6F 5) 3 ( 1), (η 5-C 5Me 5)Ti(OCH 2C 6F 5) 3 ( 2), and (η 5-C 5Me 5)Ti(OCH 2C 6F 2H 3) 3 ( 3) were synthesized via the displacement of methoxide ligands in (η 5-C 5Me 5)Ti(OMe) 3 by the corresponding aryloxy or benzyloxy ligands. These compounds have been fully characterized by various spectroscopic methods including X-ray crystallography. Compound 1 has a distorted three-legged piano stool structure. However, complexes 2 and 3 have the chariot-like structure, where chariot means a two-wheeled horse-drawn vehicle. The π electron donation of oxygen atom to Ti center in complexes 1– 3 is considerable.
