Complexes of TiX₄ (X = Cl, OCHMe₂) NEt₂) with C₂-Chiral BIS-Oxazolines

Abstract

The synthesis, characterization and spectroscopic properties of complexes of titanium with C ₂-chiral bis-oxazoline ligands of the type TiX₃L (X = Cl, OCHMe₂, NEt₂ and LH = 2,2′-methylenebis[(4S)-4-isopropyl-2-oxazoline] (MBIO), 2,2′-methylenebis[(4S)-4-tert-butyl-2-oxazoline] (MBTO) and 2,2′-methylenebis[(4S)-4-phenyl-2-oxazoline] (MBPO) have been described. Their structures and the nature of bonding of the ligands to titanium(IV) have been deduced on the basis of IR and NMR (¹H, ¹³C) spectral data. All the complexes were found to be monomeric in nitrobenzene as determined cryoscopically.
