The steric and electronic influence of various substituents at different positions of the fluorenylidene fragment effects the catalytical properties of the MAO activated bis(fluorenylidene) complexes [C13H8-nRn-(CH2)2-C 13H8-nRn]ZrCl2 (n=0-2; R=H, alkyl, aryl, -(CH)4-, -OCH3). We report the synthesis and characterization of 27 new ansa bis(fluorenylidene) zirconium dichloride complexes and illustrate their application in the homogeneously catalyzed polymerization of ethylene. The obtained results are compared with those of known bis(fluorenyl)complexes.
