The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

open access: yesChemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Solvent Effects on the Conformational Preferences of 2,6‐Pyridylcarboxamide Foldamers

open access: yesChemistry – A European Journal, EarlyView.
The marked effect of organic solvents and water/methanol mixtures on the conformational preferences of a soluble chiral foldamer has been established in a diverse array of seventeen distinct environments. ABSTRACT The marked influence of organic solvents and water on the conformational preferences of a chiral, soluble 2,6‐pyridylcarboxamide foldamer ...

Acid‐Catalyzed Rearrangement Reaction for Single‐Molecule Junction Formation

open access: yesChemistry – A European Journal, EarlyView.
Hydrazobenzenes cannot form single‐molecule devices with gold electrodes in a nonpolar solvent, but with the addition of trifluoroacetic acid, robust single‐molecule junctions are created. Hydrazobenzenes likely undergo rearrangement reactions to form benzidines, which are then attached to gold contacts by dative NH2→Au interactions for junction ...

Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.
