    摘要: Organometallic compounds of transition metals containing optionally tetrahydrogenated 2-indenyl as a first ligand of the formula wherein A represents the benzo system or the tetrahydrocyclohexyl system and the other symbols have the range of meanings given in the description, are prepared by reaction of with Mg or Zn and with a dihalide Hal2—Y—Hal3 (III) to form the novel intermediates further reaction with ZM2p(Va) or ZR9p(Vb) to form and further reaction with a transition metal compound of the formula M1Xq(VIII). Many compounds (I) are not C2-symmetrical. The compounds (I) can be used as catalysts for the (co)polymerization of olefins, diolefins and/or cycloolefins.
