Sulfur‐Boron Lewis Pair‐Catalyzed Hydrohalogenation of Alkynes via Formal Hydrogen Atom Transfer

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
A sulfur‐boron Lewis pair enables the stereodivergent hydrohalogenation of alkynes with exclusive Markovnikov selectivity. Mechanistic studies support a proton transfer‐electron transfer (PT‐ET) sequence for vinyl radical formation rather than a concerted hydrogen atom transfer (HAT) pathway.

Effective Porosity and Pore–Ligament Architecture in Mg‐Based Solid‐State Hydrogen Storage

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Magnesium (Mg)‐based hydrides offer high gravimetric capacity, high volumetric hydrogen density, elemental abundance, and low material cost, but their practical performance is constrained by coupled hydrogen transport, interfacial reaction, heat transfer, and structural evolution during repeated magnesium/magnesium hydride conversion.

Ultra‐Tough Hybrid Supramolecular Gelatin Hydrogels

Small, Volume 22, Issue 61, 2 November 2026.
Tannic acid‐mediated coacervation compacts gelatin into a dense supramolecular network while generating an acidic microenvironment that activates pre‐embedded bis‐oxazoline crosslinkers. The resulting hybrid hydrogel combines covalent stabilization with reversible energy dissipation, producing high strength, extreme extensibility, substantial toughness,

Through the Cracks: Sea Ice Regions as a Source of Volatile Marine Sulfur in the Springtime Arctic

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Marine volatile methylated sulfur compounds (VMS) including dimethyl sulfide (DMS) and methanethiol (MeSH), are important natural sources of sulfur to the atmosphere and precursors to aerosols and cloud condensation nuclei. However, observations of DMS and MeSH in regions with sea ice remain limited.

Selective N‐Functionalization of Pyrazoles

European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.
