Synthesis of (3-methoxypropyl)-cyclopentadienyltitanium and zirconium complexes
摘要:
Four titanium and zirconium complexes of (3-methoxypropyl)cyclopentadienyl, Cp2'MCl2 (M = Ti, Zr), Cp'CpTiCl2 and Cp'Cp''TiCl2 (Cp = C5H5, Cp'= MeOCH2 CH2CH2C5H4, CP'' = MeOCH2CH2C5H4), have been synthesized in good yields by reacting the potassium salt Cp'K with MCl4 (M = Ti, Zr), CpTiCl3 and Cp''TiCl3, respectively. Their IR spectra show that the oxygen atom in the side-chain does not coordinate with the central metals, while mass specta imply the coordination of oxygen with the metals is possible, in particular in some low-valent species.
