摘要

Abstract

The trichlorozirconium

-hydrazonides (R=H

A; R=CH

B) were synthesized through the finely controlled stoichiometrical reactions of anhydrous zirconium tetrachloride with the lithium salt of either 1-(furan-2-ylmethylene)-2-phenylhydrazonide or 1-(furan-2-ylethylidene)-2-phenyl hydrazonide in the solvent tetrahydrofuran (THF)

respectively. These complexes were highly sensitive to air and moisture due to solely using less bulky ligand of hydrazonides. The molecular structures of the title complexes

determined by means of single crystal X-ray diffraction

were found to be the distorted pentagonal bipyramid geometry around zirconium atom

with three chlorides and the hydrazonato ligand acting as the

-coordination mode as well as two incorporated THF molecules. Upon activation with either methylaluminoxane (MAO) or modified methylaluminoxane (MMAO)

both complexes

and

exhibited catalytic activities toward ethylene polymerization

producing polyethylenes with ultra-high molecular weights.
