摘要： The invention relates to novel immobilisable imidazolium salts of the general formulae (I) and (II) which contain a group R carrying SiR′n(OR′)3−n on one of the two nitrogen atoms and a sterically demanding cyclic hydrocarbon radical on the other of the two nitrogen atoms of the heterocyclic ring. The invention furthermore relates to the use of the compounds of the general formulae (I) and (II) as starting materials for immobilisable catalyst ligands, catalyst precursors and catalysts, and to the use as solvents in organic, organometallic and transition metal-catalysed synthesis and as catalysts in organic synthesis.

摘要： Described are catalyst systems having aluminium alkyl complexes of the formula (I) described herein applied to magnesium chloride, SiO2 or SiO2 in combination with MgCl2 as support in the presence of titanium halides or vanadium halides and internal and, if desired, external donors act both as cocatalysts and as stereoselectivity promoters in heterogeneous polymerizations of &agr;-olefins. Also described are polymerization methods using these catalyst systems.
