| Abstract: | Contributions to the Chemistry of Transition Metal Alkyl Compounds. 64 1] Preparation and Crystal Structure of BisN,N′ -bis(trimethylsilyl)-benzamidinato]dimethyltitanium Tetramethyltitanium reacts with excess N,N′-bis(trimethylsilyl)-benzamidine ( 1 ) to give bisN,N′-bis(trimethylsilyl)benzamidinato]dimethyl-titanium ( 2 ) via protolysis. This compound was isolated and characterized by X-ray crystal structure analysis. In the crystal, 2 adopts an octahedral coordination with the methyl groups in cis-positions. The monomethyl complexes PhC(NSiMe3)2]2M(Me)Cl ( 3 : M = Ti, 4 : M = Zr) have been prepared by treatment of the dichloro precursors with one equivalent of methyllithium. |
