Synthesis of ring-substituted bis-eta5-cyclopentadienyl derivatives of the Group IV elements containing the bicyclic ligands eta5-C5H3(1,2-CH2-)n, n=4, 5, or 6

Abstract

The synthesis of unsubstituted and substituted bicyclic eta5-cyclopentadienyl ligands and their Group IV metal complexes [M{eta5-C5H3(1,2-CH2–)n}2Cl2], where n=4, 5, 6 and M=Ti, Zr, Hf, is reported. An example of an ansa-bridged zirconium analogue is also described
