Syntheses and properties of the novel co-catalysts N,N-dimethylanilinium- and trityl{tetrakis[4-(trifluoromethyl)-2,3,5,6-tetrafluorophenyl]borate}
2001
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.
