CO2 Activation by Small Copper, Cobalt, and Yttrium Oxide Clusters Probed via Infrared Multiple‐Photon Dissociation Spectroscopy

open access: yesChemPhysChem, Volume 27, Issue 17, 14 September 2026.
Infrared multiple photon dissociation spectroscopy is used to study the activation of CO2 on Cu‐, Co‐, and Y‐oxide clusters. While CO2 activation is not possible on cationic clusters, the binding motif on anionic clusters depends on a fine interplay between the nature and energetic location of the molecular orbitals and the charge (oxidation state) on ...

Unraveling Terminal Cobalt–Antimony Double Bond: Breaking New Ground in Heavy Pnictogen Multiple Bonds

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
N‐heterocyclic carbenes (NHCs) function as “molecular scissors,” cleaving otherwise inert Sb═Sb bonds in distibenes to generate monomeric, zwitterionic stibinide species. These intermediates act as efficient stibinidene transfer reagents, granting access to a rare terminal cobalt–stibinidene complex.

SO2 Transfer Enabled by an Easy‐to‐Handle Ionic Liquid

open access: yesChemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Best of both worlds: The ionic liquid [NEt3Me][Cl(SO2)n] unites the atom economy and low cost of sulfur dioxide with the safety and applicability of common surrogates, streamlining SO2 transfer to access to 3‐sulfolenes, sulfonamides, and SuFEx reagents.

Truncation of Samroiyotmycin: Tailored seco‐Acids as Novel Antimalaria Compounds

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 34, 11 September 2026.
Six truncated samroiyotmycin‐derived antimalarials were synthesized by replacing the tosyloxazole unit with electron‐deficient aryl groups. The most active seco‐acid with EWG = 2 × CF3 outperformed the natural product SamA. Its enhanced activity supports a donor–acceptor interaction involving the electron‐poor aryl unit, consistent with inhibition of ...

Borylcyclopropanes: Synthetic Strategies and Applications

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...
