Synthesis of (3-methoxypropyl)-cyclopentadienyltitanium and zirconium complexes

Add time:08/04/2019    Source:sciencedirect.com

Four titanium and zirconium complexes of (3-methoxypropyl)cyclopentadienyl, Cp′2MCl2 (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 spectra imply the coordination of oxygen with the metals is possible, in particular in some low-valent species.
