Abstract
The reaction of various 9-substituted fluorene compounds (9-R-C13H9) ( R = Me(3)Si, alkyl, aryl) (1a-i) with butyllithium followed by treatme nt with (C5H5)ZrCl3 leads to unbridged fluorenyl complexes of the type (C5H5)(B-R-C13H8)ZrCl2 (2a-i). In combination with methylaluminoxane, complexes 2a-i show a high catalytic activity as homogeneous ethylene polymerization catalysts. Compounds 29 (R = Pr-i), 2d (R = cyclohexyl ), and 2e (R = (t)Bu) were characterized by X-ray structure analyses.
