    • 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.
    • 含有任选四氢化的2-茚基的过渡金属的有机金属化合物作为Formulafherein A的第一配体,表示苯并系或四氢环己基系,其它符号在描述中给出的含义范围是通过与Mg或Zn的反应和 与二卤化物Hal2-Y-Hal3(III)形成新的中间体,进一步与ZM2p(Va)或ZR9p(Vb)反应形成并进一步与式M1Xq(VIII)的过渡金属化合物反应。多种化合物(I) 不是C2对称的。化合物(I)可以用作烯烃,二烯烃和/或环烯烃的(共)聚合的催化剂。
