Description

Technical field:

[0001] The present invention relates to a class of ethylene oligomerization and post-polymerization transition metal coordination catalysts. Background technique:

[0002] Catalytic ethylene oligomerization can produce linear olefins on a large scale. The products are important organic chemical intermediates and have become an independent branch of the petrochemical industry. Catalyzed ethylene polymerization can obtain polymer materials with different properties and uses. In recent years, the research on late transition metal olefin polymerization and oligomerization catalysts has developed rapidly (Angew. Chem. Int. Ed. 1999, 38, 428-447; Chem. Rev. 2000, 100, 1169-1203).

[0003] Since the 1970s, the homogeneous catalysis of olefin polymerization and oligomerization by transition metal complexes has attracted people's attention, and people have made great efforts to study new catalysts and improve existing catalysts to improve the activity of catalysts a...
