A transition metal organometallic compound contains a 2-indenyl ligand. An organometallic compound (I) of a transition metal and an optionally substituted 2-indenyl as a first ligand is of formula (I) excluding ethylene-bis(2-indenyl)-titanium dichloride, dimethylsilyl-(1-indenyl)(2-indenyl)-bis-dimethylamino-hafnium, dimethylsilyl-(1-indenyl)(2-indenyl)-bis-dimethylhafnium, dimethyl-bis(2-indenyl)silane-zirconium dichloride, 1-cyclopentadienyl-2-(2-indenyl)-ethane-zirconium chloride, bis-(2-indenyl)methane-zirconium dichloride, ethylene-1-(3-but-3-enyl)inden-1-yl)-2-((1-but-3-enyl)-inden-2-yl)zirc onium dichloride and ethylene-1,3-((3-allyldimethylsilyl)-indene-1-yl)-2-((1-allyldimethyls ilyl)-inden-2-yl)zirconium dichloride. Independent claims are included for (i) a process for the production of (I) by mixing an optionally substituted 2-halo-indene of formula (II) with elementary Mg or Zn at (-) 20-120 degrees C in an amount of 1-100 g Mg or Zn per mole of indene and following separation of unreacted Mg or Zn, mixing with a dihalide of formula (III) in an amount of 1-20 moles per mole of indene (the addition of dihalide may occur simultaneously with that of Mg or Zn). The resulting intermediate reaction product (II) of formula (IV) is mixed with a Z-derivative of formula (Va) or (Vb) (optionally after isolation of (II)) with formation of M<2>Hal<3> and/or R<9>Hal<3>, optionally in the presence of a base to form a 2-indenyl compound of formula (VI) with addition of a transition metal compound of formula (VII); (ii) tert-butylamido-2-indenyl-dimethylsilyl-titanium dichloride; (iii) the intermediate reaction product (II); and (iv) the preparation of (II).
