The Formation of Covalent Linkages in Lignocellulosic Biomass via the Oxocarbenium Intermediate

open access: yesChemPhysChem, Volume 27, Issue 4, 25 February 2026.
Density functional theory models show that the hydrated and acidic hemicellulose matrix in lignocellulosic biomass can generate oxocarbenium ions. These reactive intermediates can participate in the stable formation of glycosidic lignin‐carbohydrate covalent linkages, promoting recalcitrance in plant biomass.

An Unorthodox Enolate–Triggered Radical Relay Directs the Chemo Upgrading of Levulinic Acid Into Citramalic Acid

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
Unorthodox Thermodynamic Enolate Coupled with a Radical Pathway A transition‐metal‐free oxidation of biomass‐derived levulinic acid to citramalic acid is achieved through an unorthodox enolate in combination with a radical pathway using potassium tert‐butoxide (KOtBu) and molecular oxygen (O2).

Dispersion‐Enhanced Nitrogen‐Centered Photocatalysis of the Direct Hydrogen Atom Transfer

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Nitrogen‐centered acridine photocatalysts for direct hydrogen atom transfer have been developed, leveraging dispersion interactions to enhance photocatalytic activity. This approach enables diverse functionalization reactions of strong C─H bonds even under cryogenic conditions and provides a new strategy for boosting the efficiency of direct HAT ...
