Macrocyclic-Constrained Bulky Binuclear Nickel Catalyst for Ethylene (Co)Polymerization Click to copy article link Article link copied!
Abstract Click to copy section linkSection link copied! In nickel-catalyzed olefin (co)polymerization, simultaneously achieving high polar monomer incorporation, high molecular weight, and precise control over chain walking and branching remains a central challenge. Herein, we report an α-diimine nickel catalyst that integrates macrocyclic structural constraint, strong ortho-aryl steric shielding, and a binuclear framework.

Investigations of flexible cycloalkyl substituents on pyridine‐imine based nickel(II)‐ and palladium(II)‐catalyzed ethylene oligomerization
INTRODUCTION Over the last two decades, much progress has been made in the field of palladium- and nickel-complex-catalyzed ethylene polymerization and oligomerization.1-10 Due to their unique ability to incorporate polar functionalized comonomers and to undergo chain walking, numerous novel polyolefins with distinct microstructures were synthesized.

Dearomatized Diimines for Nickel(II) and Palladium(II) Catalyzed Ethylene Polymerization and Copolymerization
Dearomatized Diimines for Nickel(II) and Palladium(II) Catalyzed Ethylene Polymerization and Copolymerization Steric tuning on the aryl ortho-positions and backbone of the α-diimine pro-ligand significantly impacts Ni(II) and Pd(II)-catalyzed olefin (co)polymerization. Herein, the dual steric enhancement on the ortho-positions and backbone was achieved through the combined bulky vicinal t-butylated dearomatized acenaphthyl backbone and bulky ortho substituents (i-Pr or CHAr2).

Adaptive Functions of Structural Variants in Human Brain Development
Abstract Quantifying the structural variants (SVs) in nonhuman primates could provide a niche to clarify the genetic backgrounds underlying human-specific traits, but such resource is largely lacking. Here, we report an accurate SV atlas in a population of 562 rhesus macaques, verified by two public SV benchmarks, an inhouse benchmark of eight macaque genomes with long-read sequencing and another inhouse benchmark of one macaque genome with whole-genome assembly.
Financial and Logistical Service Strategy of Third-Party Logistics Enterprises in Cross-Border E-Commerce Environment
Abstract : As competition in the cross-border logistics-service market intensifies and demand rises, enterprises with third-party logistics (3PL) combine logistical and financial services to provide comprehensive services. This study considers a secondary supply chain consisting of a cross-border e-commerce enterprise and a 3PL enterprise. When cross-border e-commerce enterprises lack funds, 3PL enterprises can provide them with inventory pledge loans.
