Structural and Spectroscopic Evidence of Hydrogen Bonded Anionic Wires in Protic Ionic Liquids

ChemPhysChem, Volume 27, Issue 19, 14 October 2026.
Anionic wires of deprotonated carboxylic acids challenge the general wisdom that like charges repel. The hydrogen bond motif observed in the X‐ray structure is even preserved in the liquid state of the material as shown by δ1H NMR spectroscopy. The experimental and theoretical findings provide deep insight into the nature of hydrogen bonding.

Encapsulation of Porphyrins in Polymer Microgels and Microbeads for Heterogeneous Photooxidation

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Amino‐ or ammonium‐functionalized tetraphenylporphyrins were synthesized and encapsulated within polymers to form microgels and microbeads that act as heterogeneous photocatalysts. Photooxidation in aqueous media quantitatively converts sulfides and aldehydes into sulfoxides and carboxylic acids via the singlet‐oxygen pathway, demonstrating an ...

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species

The Expanding Role of Diazirines in Synthetic Methodology

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
Beyond their established role in photoaffinity labeling, diazirines have emerged as versatile reagents in synthetic chemistry. This review highlights their dual reactivity as carbene and nitrogen‐transfer precursors, showcasing mechanistic insights and diverse applications in cyclopropanations, cycloadditions, skeletal editing, amination, heterocycle ...
