Abstract
The reaction of indenyllithium, IndLi, with CpMCl(3) (M = Ti, Zr) or C p MCl(3) (M = Zr, Hf) leads to complexes of the type (L)(Ind)MCl(2) ( 1: L = Cp, M = Ti; 2: L = Cp, M = Zr; 3: L = Cp, M = Zr; 4: L - Cp*, M = Hf). In combination with methylaluminoxan (MAO), complexes 1-4 sho w a high catalytic activity as homogeneous ethylene polymerization cat alysts. The ethylene selective catalyst precursor 3 was characterized by an X-ray structure analysis.
