Recent progress on nickel-based complex pre-catalysts is reviewed herein. The ethylene
oligo-/polymerization behaviour is discussed in terms of the variation of the complex models …

Bicyclic guanidines have physical, electronic and chemical properties that differentiate them
from their acyclic counterparts, with many of these characteristics directly imposed by the …

A new family of highly active ethylene tri-/tetramerization catalysts based on N-
phosphinoamidinechromium complexes has been investigated. The 1-hexene to 1-octene …

Computational design of molecular homogeneous organometallic catalysts followed by
experimental realization remains a significant challenge. Here, we report the development …

Linear alpha-olefins are widely used in the petrochemical industry and the world demand for
these compounds increases annually. At present, the main method for producing linear …

A series of 2, 6-dibenzhydryl-N-(2-phenyliminoacenaphthylenylidene)-4-chloroanilines (L1–
L5) and their nickel halide complexes LNiX2 (X= Br, C1–C5; X= Cl, C6–C10) were …

Pyrazolyl ligands have been used to prepare metal complexes since the mid-1960s as
nitrogen-donor ligands. However, unlike other nitrogen-donor ligands like imines and …

A series of N-(2-substituted-5, 6, 7-trihydroquinolin-8-ylidene)-arylaminonickel (II)
dichlorides were synthesized by the one-pot stoichiometric reaction of nickel dichloride, 2 …

The reactions of 2, 6-bis (3, 5-dimethylpyrazol-1-ylmethyl) pyridine (L1) and 2, 6-bis (3, 5-di-
tert-butylpyrazol-1-ylmethyl) pyridine (L2) with NiCl2 or NiBr2 gave the nickel (II) complexes …

Abstract The β-diimine ligands 2-(phenyl) amine-4-(phenyl) imine-2-pentene and 2-(2, 6-
