资源简介：
New chromium(III), iron(II), and cobalt(II) complexes
of acyclic
1,3-bis[(2,6-dimethylphenylimino)ethyl and benzyl]imidazol-2-ylidene
were prepared from the corresponding silver or copper adduct as transmetalating
agent or from in situ deprotonation of the parent imidazolium salt.
The catalytic activities of all three complexes were evaluated for
ethylene polymerization at atmospheric pressure and room temperature
with activation by methylaluminoxane. The Cr(III) complexes were found
to be the most active, with a rate of 35 kg PE mol–1 Cr h–1.
