摘要: [(η1-Flu)Ti(μ-OiPr)(OiPr)2]2 (1) and (η1-Flu)(η5-Flu)Ti(OiPr)2 (2) were easily prepared from FluLi ClTi(iPrO)3 demonstrated a remarkable thermal stability in comparison with known (fluorenyl)titanium complexes. Both complexes characterized by X-ray analysis temperature-dependent NMR spectroscopy. In combination methylaluminoxane, both compounds are highly efficient initiators for styrene polymerization, producing syndiotactic polymers.
