Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

open access: yesChemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Phosphorescence of Heavy, T‐Shaped Pnictogen Trisamides in Solution at Room Temperature in the Near‐Infrared II Region

open access: yesChemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
The unique photophysical properties of heavy T‐shaped Sb and Bi trisamides are reported. A ligand‐to‐pnictogen charge‐transfer excitation from a redox‐active NNN pincer to a vacant pnictogen p‐orbital populates a triplet state that emits in the highly desirable NIR‐II region, with lifetimes up to the µs range.

Immunomodulatory Potential of Quinoline Q3, a Selective Inhibitor of the Canonical NF‐κB Pathway in Macrophages

open access: yesChemMedChem, Volume 21, Issue 13, 14 July 2026.
The quinolone Q3 specifically enhances the DNA binding of the p50/p50 NF‐κB dimers, while inhibiting the activity of the p65 transcriptional activator, resulting in inhibition of the NF‐κB canonical pathway in lipopolysaccharide (LPS)‐stimulated macrophages.

Catalytic Functionalization of Unactivated π‐Bonds Enabled by Bidentate Directing Auxiliaries

open access: yesAngewandte Chemie, Volume 138, Issue 28, 6 July 2026.
This review explores how bidentate directing auxiliaries have advanced transition‐metal catalysis for unactivated alkene/alkyne functionalization. By leveraging chelated intermediates, bidentate directing auxiliaries enable precise hydrofunctionalization, difunctionalization, and C─H activation of π‐bonds with unique selectivity and reactivity.
