Highly Unsaturated Lignin Through Clean and Efficient Ru‐Catalyzed Glycerol Carbonate Allylation and Ring‐Opening Reaction Strategies

open access: yesChemSusChem, Volume 19, Issue 18, 28 September 2026.
An innovative, ruthenium‐catalyzed strategy successfully functionalizes unpurified technical lignins with ready‐to‐graft allylic synthons derived from glycerol carbonate. This atom‐economical ring‐opening reaction achieves up to 90% hydroxyl substitution.

Virus‐Mediated Self‐Assembly of Functional Cyclodextrins for Antiviral Inhibition

open access: yesAngewandte Chemie, Volume 138, Issue 38, 14 September 2026.
A sialic acid (SA)‐functionalized cyclodextrin (CD) self‐assembles on SARS‐CoV‐2 through ligand–receptor recognition, nucleating cooperative supramolecular polymer growth that blocks infection. The adaptive assembly requires both ligand binding and host–guest polymerization, remains active across variants, and can be tuned by coassembly, establishing ...

A New Switchable Zr12 Oxocluster Based Large Pore Metal–Organic Framework Functionalized With Spin Crossover Complexes for Acetic Acid Colorimetric Sensing

open access: yesAngewandte Chemie, Volume 138, Issue 38, 14 September 2026.
We present here (1)⊂MIP‐216(Zr), a new hybrid material composed of an FeII spin crossover complex (1) loaded in the pores of a new hydrophobic metal–organic framework (MIP‐216(Zr), that presents a high affinity toward acetic acid and acts as a highly sensitive colorimetric sensor of acetic acid vapor due to a spin state switching of the encapsulated ...

Nucleophilic Trifluoromethoxylation of Acyl Chlorides: A Direct Route to Trifluoromethyl Esters

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.
A new method for the synthesis of the underexplored trifluoromethyl carboxylic esters using acyl chlorides as readily available feedstocks and in situ‐generated AgOCF3 from silver fluoride and the trifluoromethyl para‐toluenesulfonate has been designed. The reaction works on a large variety of aromatic and aliphatic acyl chlorides, while minimizing the
