The heterobimetallic CpFe(μ-η5: η5-as-indacenediide)RhL2 complexes (L2 = COD (2), NBD (3), (ethylene)2 (4)) have been obtained from metalation of the mononuclear lithium CpFe(η5-as-indacenediide) with [Rh(μ-Cl)L2]2. Mixtures of syn and anti heterobimetallic complexes were formed and fully characterized by 2D NMR spectroscopy. The reactivity at the rhodium center is greatly influenced by the presence

This contribution describes the synthesis and characterization of bimetallic zirconium metallocene derived from unsubstituted 1,8-dihydro--indacene (-IcH). The complex [(Cp*ZrCl)--Ic] was synthesized from the dilithiated salt of -indacene [-Ic][Li] with two equivalent of [(Cp*ZrCl)]. This complex here reported was characterized by means of H and C NMR, elemental analysis, and X-ray diffraction. In
该贡献描述了衍生自未取代的 1,8-二氢-indacene (-IcH) 的双金属锆茂金属的合成和表征。配合物[(Cp*ZrCl)--Ic]由-二茚[-Ic][Li]的二锂盐与两当量的[(Cp*ZrCl)]合成。本文报道的这种配合物通过 1H 和 13C NMR、元素分析和 X 射线衍射进行了表征。为了进一步了解其催化行为,该配合物在乙烯聚合催化中进行了测试,显示出最高的活性。对锆化合物进行了理论计算,以有助于进一步了解这种新型烯烃催化剂的机理。
