A series of 2,6-dibenzhydryl-N-(2-phenyliminoacenaphthylenylidene)-4-methylbenzenamines (L1−L5) and the nickel(II) dibromide complexes thereof (C1−C5) were synthesized fully characterized. The molecular structures representative determined by single-crystal X-ray diffraction revealed a distorted-pyramidal geometry at nickel. All procatalysts exhibited very high activity for polymerization ethylene, with activities as range 107 g PE (mol Ni)−1 h−1.

Single-crystal X-ray diffraction revealed a distorted tetrahedral geometry around nickel center in C3, C5 C9. Upon activation with modified methylaluminoxane (MMAO), all pro-catalysts performed high activities ethylene polymerization, producing highly branched...
Abstract A series of 2‐(1‐{2,6‐bis[bis(4‐fluorophenyl)methyl]‐4‐methylphenylimino}ethyl)‐6‐ [1‐(arylimino)ethyl]pyridine ligands is synthesized and fully characterized. The corresponding iron complexes are prepared characterized by single‐crystal X‐ray diffraction for representative complexes, among other methods, revealing a pseudo square‐pyramidal geometry at the center. Upon activation with MMAO, all precatalysts exhibit high activity in ethylene polymerization, producing linear...
A series of cobalt(II) dichloride complexes ligated by 2-[1-(2,4-dibenzhydryl-6-methylphenylimino) ethyl]-6-[1-(arylimino)ethyl]pyridines was synthesized and characterized FT-IR spectroscopy elemental analysis. The molecular structure the representative complex Co4 (R1 = Me, R2 Me) confirmed as pseudo square-pyramidal geometry at cobalt single-crystal X-ray diffraction. Upon treatment with co-catalysts MAO or MMAO, all pre-catalysts exhibited high activities up to 1.81 × 107 g PE mol−1(Co)...
Selected results for the synthesis of cyclic olefin copolymers (COCs)—especially copolymerizations norbornene (NBE) or tetracyclododecene (TCD) with ethylene and α-olefins (1-hexene, 1-octene, 1-dodecene)—using group 4 transition metal (titanium zirconium) complex catalysts have been reviewed. Half-titanocenes containing an anionic ancillary donor ligand, Cp’TiX2(Y) (Cp’ = cyclopentadienyl; X halogen, alkyl; Y ligand such as aryloxo, ketimide, imidazolin-2-iminato, etc.), are effective...
Acyclic diene metathesis (ADMET) polymerization of an α,ω-diene monomer bis(undec-10-enoate) with isosorbide (M1) using a RuCl2(IMesH2)(CH-2-O i Pr-C6H4) (HG2, IMesH2 = 1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene) catalyst and conducted at 50 °C (in vacuo) in ionic liquids (ILs) afforded higher-molecular-weight polymers (P1, Mn 32 200-39 200) than those reported previously (Mn 5600-14700). 1-n-Butyl-3-methyl imidazolium hexafluorophosphate ([Bmim]PF6) 1-n-hexyl-3-methyl...
Highly efficient synthesis of cyclic olefin (CO) copolymers with high glass transition temperatures (Tg) as well catalytic activity have been attained not only by copolymerization norbornene (NBE) α-olefins (1-hexene, 1-octene, 1-dodecene), but also tetracyclododecene (TCD) using half-titanocene catalysts, Cp′TiCl2(N═CtBu2) [Cp′ = tBuC5H4 (1), Cp (2)] in the presence MAO.

Molecules interacting with CasL (MICALs) are critical mediators of cell motility that act by cytoskeleton rearrangement. However, the molecular mechanisms underlying regulation cancer invasion remain elusive. The aim this study was to investigate potential role one member MICALs, i.e., MICALL2, in and function ovarian cells. We showed bioinformatics analysis MICALL2 expression significantly higher tissues advanced-stage associated poor overall survival patients. strongly correlated...
