Stereorigid titanocene and zirconocene derivatives. Synthesis and crystal-structure of the dialkyl complex [η5-η-5-(C5H4)2Si(CH3)2]Ti[CH2Si(CH3)3]2
Reaction of M2′[(η5-C5H4)2Si(CH3)2] (M′ = Li, Na, K) with MCl4 produced the known complexes [(η5-C5H4)2Si(CH3)2]MCl2 (M = Ti (1) and Zr (2). Along with the predominant product in each case a new titanium and zirconium compound is isolated. Treatment of the complexes 1 and 2 with LiCH2Si(CH3)3 gives...

| Sumario: | Reaction of M2′[(η5-C5H4)2Si(CH3)2] (M′ = Li, Na, K) with MCl4 produced the known complexes [(η5-C5H4)2Si(CH3)2]MCl2 (M = Ti (1) and Zr (2). Along with the predominant product in each case a new titanium and zirconium compound is isolated. Treatment of the complexes 1 and 2 with LiCH2Si(CH3)3 gives the novel derivatives [(η5-C5H4)2Si(CH3)2]M[CH2Si(CH3)3]2 (M = Ti (4) and Zr (5)) which have been characterized by NMR and mass spectrometry and in the case of 4 by an X-ray structural determination. |
