The invention relates to an indenyl compound of the general formula in which the symbols have the following meanings: Ind: an indenyl group R': a substituent, other than hydrogen, to the Ind group, Cp: a cyclopentadienyl group M: a transition metal from group 3, 4, 5 or 6 of the Periodic System of Elements Q: a ligand to M and k is an integer linked to the valence of M. The invention is characterized in that the R' group is bound to the Ind group at the 2-position. The indenyl compound is a catalyst component for the polymerization of olefins. The invention also relates to polymers obtainable with such indenyl compounds.

3-(Methylthio)indene (13), obtained from lithium 1-indenide (10) and dimethyl disulfide (11), reacts with methyl iodide to form truxene (14) and with methyl fluorosulfonate to form 2-(3-indenyl)-3-(methylthio)indene (16).Nucleophilic substitution of 1-chloro-2,3-dimethyl-5,6-(methylenedioxy)indene (22) with thiolates allows the isolation of the thioethers 23A/23B, which were alkylated with trialkyloxonium salts to give the stable sulfonium tetrafluoroborates 24.Deprotonation of 24 leads to extensive decomposition.The thioethers 28 have been prepared from 2-indanone (26).Their alkylation leads to the formation of (2-indenyl)sulfonium tetrafluoroborates 29.Deprotonation of 29a yields 2-(dimethylsulfonio)indenide (6), characterized by NMR spectroscopy.
