Treatment of Ti(N t Bu)Cl 2 (py) 2 ( 1 , py = pyridine) with bulky heteroallylic ligands in a 1:1 molar ratio affords the monosubstituted derivatives [PhC(NSiMe 3 ) 2 ]Ti(N t Bu)Cl(py) 2 ( 2 ), [MeOC 6 H 4 C(NSiMe 3 ) 2 ]Ti(N t Bu)Cl(py) ( 3 ), and [Ph 2 P(NSiMe 3 ) 2 ]Ti(N t Bu)Cl(py) ( 4 ). Similarly, 2:1 reactions afforded the disubstitution products [PhC(N i Pr) 2 ] 2 Ti(N t Bu)(py) ( 6 ) and [Ph 2 P(NSiMe 3 ) 2 ] 2 Ti(N t Bu) ( 7 ). The bis(pyridine) adduct Ph 2 P(NSiMe 3 ) 2 Li(py) 2 ( 5 ) was isolated as a by‐product during the preparation of 4 . The molecular structures of 7 has been established by X‐ray crystallography.
