Synthesis and Characterization of Titanium Complexes Containing Potentially Tridentate Amido-cyclopentadienyl Ligands
Two new titanium complexes of the general type Ti(η5:η1‐C5H4SiMe2NCH2CH2X)Cl2 (X = NMe2 OMe), containing a tridentate ligand, were prepared by reaction of Ti(η5‐C5H4SiMe2Cl)Cl3 with the lithium amide Li(NHCH2CH2X) (X = NMe2, OMe). The 1HNMR chemical shifts for the protons of the ethylene link were...

| description | Two new titanium complexes of the general type Ti(η5:η1‐C5H4SiMe2NCH2CH2X)Cl2 (X = NMe2 OMe), containing a tridentate ligand, were prepared by reaction of Ti(η5‐C5H4SiMe2Cl)Cl3 with the lithium amide Li(NHCH2CH2X) (X = NMe2, OMe). The 1HNMR chemical shifts for the protons of the ethylene link were found to vary considerably as a function of the temperature, indicating the presence of an equilibrium between the tri‐ and bidentate bonding mode of the ligand. A single‐crystal X‐ray structural analysis of Ti(η5:η1C5H4SiMe2NCH2CH2OMe)Cl2 revealed that the methoxy function is not intramolecularly coordinated in the solid state. |
