- W2073078143 abstract "The reaction of various fluoren compounds C13H7R1R2R3(R1, R2 H, Me, Et, 1Bu; R3 H, cyclohexyl Me3Si) with butyllithium followed by treatment with (C5Me5)MCl3 (M Zr, Hf) leads to unbridged metallocene dichloride complexes of the type (C5Me5)(C13H6R1R2R3)MCl2 (1–11). In combination with methylaluminoxane (MAO), complexes 1–11 show catalytic activity in homogeneous olefin polymerization. The crystal structures of (C5Me5)(2,7-Me2C13H7)MCl2 (M Zr (3), Hf (4)) have been determined by single crystal X-ray diffraction. Die Reaktion von verschiedenen Fluorenderivaten C13H7R1R2R3 (R1, R2 H, Me, Et, 1Bu; R3 H, Cyclohexyl, Me3Si) mit Butyllithium führt zu den entsprechenden Fluorenylanionen, die sich mit (C5Me5)MCl3 (M Zr, Hf) zu unverbrückten Metallocendichloridkomplexen des Typs (C5Me5)(C13H6R1R2R3)MCl2 (1–11) umsetzen lassen. In Verbindung mit Methylaluminoxan (MAO) erweisen sich die Komplexe 1–11 als aktive Katalysatoren bei der homogenen Olefinpolymerisation. Die Komplexe (C13Me5(2,7-Me2-C13H7)MCl2 (M Zr (3), Hf (4)) konnten mittels Röntgenstrukturanalyse charakterisiert werden." @default.
