Abstract

Zirconium complexes of two dianionic amine bis(phenolate) ligands have been synthesized, their X-ray structures solved, and their activity as hex-1- ene polymerization catalysts studied; upon treatment with B(C₆F₅)₃, as octahedral [ONNO]Zr[CH₂Ph]₂ complex, having an extra N-donor group on a side arm, shows exceptionally high polymerization activity and yields a high molecular weight poly(hex-1-ene) whereas a related pentacoordinate[ONO]Zr[CH₂]Ph)₂ complex, having on extra donor group, shows only poor activity as a polymerization catalyst.
