An Experimental and Theoretical Investigation of the Ethylene Oligomerization Reactions Catalyzed by Heterocyclic (Pyrazolyl)Imine Fe(II) and Co(II) Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Monometallic iron(II) and cobalt(II) complexes derived from potential hemilabile heterocyclic (pyrazolyl)imine catalyze ethylene oligomerization reactions upon activation with either EtAlCl2 or MAO to give predominantly butenes and hexenes. The catalytic activities are largely controlled by the complex structure and stabilization from the coordinated ...

Targeting Ubiquitin-Specific Protease 7 with Novel 5-Amino-Pyrazole Inhibitors: Design, Synthesis, and Biological Evaluation. [PDF]

open access: yesChemMedChem
Ubiquitin‐specific protease 7 (USP‐7) is a novel target for anticancer therapy. To further extend the structure–activity relationships of the previously USP‐7 inhibitor STIRUR‐41, a library of 5‐aminopyrazoles is reported. 1d shows a potency comparable to lead compound STIRUR‐41 and promising in silico and in vitro pharmacokinetic properties ...

Variable Coordination of Peroxide in a Dinuclear Copper Mono‐Oxygenase Model Complex Supported by a Pyridazine‐Bridged Ligand

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Variable coordination of peroxide: The reaction of the Cu(I) complex‐based on the BPMPD ligand with O2 at low temperatures initially led to a μ‐1,2 peroxo species (Cu2O2). By addition of an acid (lutidinium triflate), this species can be reversibly converted into a μ‐1,1‐hydroperoxo complex, which is monitored using UV/Vis spectroscopy and X‐ray ...

DMAPO/Boc2O‐Mediated One‐Pot Direct N‐Acylation of Sulfoximines with Carboxylic Acids

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The one‐pot direct N‐acylation of NH sulsoximines with carboxylic acids is described. The method can be performed under mild low‐temperature reaction conditions and exhibits a wide substrate scope (> 60 examples). The present method is operationally simple, scalable, and practical; thus, it can find wide applications in both academic and industrial ...

Cross‐Coupling Reactions in Aqueous Micellar Media

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Aqueous micellar media have emerged as sustainable alternatives to organic solvents for small‐molecule synthesis. This Review discusses the evolution of surfactants for synthesis, their application to cross‐coupling reactions, the benefits for reactivity and sustainability, and the remaining challenges in this rapidly growing field.
