摘要

Abstract

A series of nickel halides bearing 2

4-di-

-butyl-6-(quinolin-8-yliminomethyl) phenolate ligands was synthesized and characterized by IR spectroscopy and elemental analysis. Molecular structures of C1 (R = H

X = Br) and C2 (R = H

X = Cl) were further confirmed by single-crystal X-ray crystallographic studies

and revealed a distorted square planar geometry at nickel. Upon activation with diethylaluminum chloride (Et

AlCl)

all nickel pre-catalysts displayed good catalytic activity [up to 9.3 × 10

g mol

−1

(Ni) h

−1

] for ethylene oligomerization with major dimerization. In the presence of methylaluminoxane (MAO)

the nickel complex C1 was capable of ethylene polymerization under 3 MPa

and produced polyethylene products with narrow polydispersity (1.16−1.73) and molecular weights in the range of 2.6−4.95 kg/mol.
