The Dithiirane–Thiosulfine Equilibrium Revisited—A Computational Study of Structure, Thermodynamics and Kinetics

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 6, June 2026.
The dithiirane–thiosulfine equilibrium has been revisited by means of modern computational chemistry tools to shed light on whether stable thiosulfines might be isolated. ABSTRACT Thiosulfines as reactive S‐centered 1,3‐dipoles undergoing (3 + 2)‐cycloadditions are still of interest in the chemistry of sulfur‐rich heterocycles.

Hydrogen‐Bonded Molecular Clusters Transform into Surface‐Passivated Fluorophores in Carbon Nanodots: Mechanistic Insight and Sensing Application Toward Bilirubin and Cu2+ Ions

open access: yesChemPhysChem, Volume 27, Issue 9, 14 May 2026.
The present study demonstrates the transformation of dual‐emissive H‐bonded molecular clusters of fluorophores into single emissive amorphous carbon nanodots and their structure‐property relationship in fluorescence‐based sensing of Bilirubin and Cu2+ ions. The present study aims to explore the origin of fluorescence in nitrogen‐doped carbon dots (NCDs)

1,4‐Pentanediol as an Alternative Biomass‐Derived Medium for the Phosphine‐Free Heck Coupling Reactions

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
In this research, a phosphine‐free Heck coupling reaction was performed using biomass‐derived 1,4‐pentanediol and a polar protic solvent. It was demonstrated that a wide scope of products could be isolated by a simple filtration, eliminating the high‐solvent‐consuming column chromatography and reducing the E‐factor by more than 90% compared to ...

Flow Chemistry Meets Green Solvents: Telescoped Synthesis of Triazolyl Phosphoramidates and Phosphinamides in γ‐Valerolactone

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
A telescoped three‐step continuous flow process enables the synthesis of organophosphorus 1,2,3‐triazoles in the biomass‐derived solvent γ‐valerolactone (GVL). The sequence integrates N‐phosphorylation, azidation, and Cu(I)‐catalyzed azide–alkyne cycloaddition (CuAAC), followed by in‐line copper removal, giving diverse triazoles in good to high overall

Solvent‐Controlled Electrochemical Cyclization of Areneazo‐2‐(2‐nitro)propanes to Benzo[c]cinnolines

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Solvent‐mediated redox pathway control enables the first electrochemical cyclization of areneazo‐2‐(2‐nitro)propanes to benzo[c]cinnolines. Mixed solvent systems containing hexafluoroisopropanol (HFIP) and MeOH additives widen the redox potential gaps and stabilize diazonium intermediates via hydrogen bonding, favoring oxidative intramolecular ...

Desymmetrization of Pseudo‐para Diformyl[2.2]Paracyclophane via Brønsted Acid‐Catalyzed Reductive Amination

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A highly stereoselective desymmetrization of pseudo‐para diformyl[2.2]paracyclophanes is developed via chiral Brønsted acid‐catalyzed reductive amination. This protocol provides efficient access to enantiopure planar chiral paracyclophanes with broad substrate scope, excellent enantioselectivity, and versatile postsynthetic functionalization. Access to

Sustainable and Direct Recovery of Lithium‐Ion Battery Cathodes From Production Scraps

open access: yesChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Lithium‐ion batteries (LIBs) represent the dominant energy storage technology, and as their demand continues to rise, the efficient recycling and recovery of critical elements from their cathodes become increasingly important. Direct recovery of active electrode materials from spent LIBs or electrode manufacturing scraps offers an effective strategy to
