Amido functionalized ansa fluorenylidene half-sandwich complexes of zirconium as catalyst precursors for homogeneous ethylene polymerization
Amido functionalized ansa fluorenylidene half-sandwich complexes of zirconium have been prepared and characterized. After activation with methylalumoxane (MAO) these complexes can be used for catalytic ethylene polymerization. The variation of the substituent on the terminal nitrogen atom has a considerable influence on the catalyst activity.
