Abstract
Abstract The syntheses and characterization of the novel co-catalysts trityl{tetrakis[4-(trifluoromethyl)-2,3,5,6-tetrafluorophenyl]borate} (2) and the corresponding N,N-dimethylaniliniumborate (3) is reported. Activation of dimethyl[rac-ethylenebis(indenyl)]zirconium(IV) with 2 or 3 forms a catalyst system for the homogeneous polymerization of ethene and propene, but also catalyzes the polymerization of 1-hexene. The molecular structure of the new, {tetrakis[4-(trifluoromethyl)-2,3,5,6-tetrafluorophenyl]borate} anion was determined by single-crystal X-ray structure analysis.
