Silylium‐Ion‐Initiated Disulfidation of Internal Alkynes With Disulfides

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Silylium‐ion initiation enables the disulfidation of internal alkynes with diaryl disulfides. The catalytic turnover is maintained by the sulfonium ion ArS(ArSSAr)+ as a sulfenium‐ion carrier that reacts with an alkyne to form a thiirenium ion. Its ring opening by disulfide addition yields the 1,2‐bis(arylthio)‐substituted alkene product with E:Z > 95 ...

Cycloazulenylene

Angewandte Chemie International Edition, Volume 65, Issue 37, 7 September 2026.
A strained macrocycle consisting solely of azulene subunits, named [6]cycloparaazulenylene ([6]CPA), is presented. The macrocycle exhibits a notably narrow HOMO–LUMO gap for a pristine azulene species, strain‐induced red‐shifted absorption, and an unusual tubular packing motif elucidated via single‐crystal XRD.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, Volume 600, Issue 17, Page 2579-2614, September 2026.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation

Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.
