  Group 4 ansa-metallocene Ziegler catalysts derived from trans-1,2-cycloalkylene-bis(indenyl)- and -bis(tetrahydroindenyl)MCl2 systems: structural and reactivity studies

  摘要：

  A series of trans-1,2-cycloalkylene-bridged bis(indenyl)MCl2 complexes (M = Ti, Zr, Hf) with bridging hydrocarbyl moieties ranging from five-to eight-membered rings, and their corresponding bis(tetrahydroindenyI)MCl2 complexes were prepared. In each case a mixture of two racem-like (rl, rl') and one meso-like (ml) diastereoisomers was obtained. Chromatographic separation and recrystallization gave the pure ansa-bis(tetrahydroindenyl)TiCl2 complexes 7a-ml, 7b-rl, 7b-ml, and 7c-ml with bridging cyclopentylene, cyclohexylene, and cycloheptylene moieties, respectively, that were characterized by X-ray diffraction. Activation of the Ti-, Zr-, and Hf-complexes with methylalumoxane gave active homogeneous Ziegler catalysts that were employed in propene polymerization reactions. In each case the meso-like diastereoisomers were practically inactive compared to the isomeric racem-like systems, as could be expected from the pronounced shielding of the metal center observed in the X-ray crystal structure analyses of the meso-like trans-1,2-cycloalkylene-bis[1-(4,5,6,7-tetrahydroindenyl)]TiCl2 complexes.
