Catalysts containing metallocenes with arylsubstituted indenyl derivatives as ligands, process and intermediates for the preparation of these metallocenes and their use

摘要

Catalysts consisting of a metallocene of formula (I) and a cocatalyst are claimed, M<1> = a Group IVb, Vb or VIb metal; R<1>, R<2> = H, 1-10C alkyl or alkoxy, 6-10C aryl or aryloxy, 2-10C alkenyl, 7-40C aralkyl or alkaryl, 8-40C aralkenyl, OH or halogen; R<3> = H, halogen, optionally halogenated 1-10C alkyl, 6-10C aryl, N(R<16>)2, SR<16>, OSi(R<16>)3, Si(R<16>)3 or P(R<16>)2 (with R<16> = halogen, 1-10C alkyl or 6-10C aryl); R<4>-R<12> = as for R<3>, or adjacent groups may form part of one or more aromatic or aliphatic rings, or the groups R<5> and R<8> or R<12> may form such rings with the attached atoms; R<13> = -X-, -X-X-, -Y-Y-, -O-X-O- -Y-, -O-X-, -Y-X-, -Y-Y-Y-, =BR<14>, =AlR<14>, -O-, -S-, =SO, =SO2, =NR<14>, =CO, =PR<14> or =P(O)R<14>; X = -M<2>R<14>R<15>-; Y = -CR<14>R<15>; R<14>, R<15> = H, halogen, 1-10C alkyl, fluoroalkyl or alkoxy, 6-10C aryl, fluoroaryl or aryloxy, 2-10C alkenyl, 7-40C aralkyl or alkaryl, or 8-40C aralkenyl, or R<14> + R<15> + the attached atoms may form ring(s); M<2> = silicon, germanium or tin. Also claimed are: (i) polyolefins obtained by (co)polymerisation of olefins of formula Ra-CH=CH-Rb (with Ra, Rb = H or 1-14C hydrocarbyl, or Ra + Rb may form part of one or more rings) at -60 to 200 degrees C and 0.5-100 bar in solution, suspension or gas phase, in presence of these catalysts; (ii) a process for the production of metallocenes (I); and (iii) intermediate indanones, indenes and bridged ligand systems formed in this process.
