On the Environmentally Friendly Synthesis of 2‐Hydroxyethyl Furan‐5‐Carboxylic Acid (MHEF) and bis(2‐Hydroxyethyl) Furan‐2,5‐Dicarboxylate (BHEF)

ChemistryOpen, EarlyView.
To better understand how the biocatalyzed depolymerization of polyesters works, model molecules are needed to develop activity assays and determine enzymatic kinetic parameters. In this communication the chemical synthesis and characterization of 2‐hydroxyethyl furan‐5‐carboxylic acid and bis(2‐hydroxyethyl) furan‐2,5‐dicarboxylates as potential model ...

One‐Step Aqueous Synthesis of Glycosyl Pyridinium Salts, Electrochemical Study, and Assessment of Utility as Precursors of Glycosyl Radicals Using Photoredox Catalysis

ChemistryOpen, EarlyView.
Unprotected glycosyl pyridinium salts may be accessed in a single step from the corresponding unprotected sugar in aqueous solution. Whilst meta‐ and para‐substitution is well tolerated, ortho substitution of the N‐heterocycle inhibits product formation. Electrochemical studies revealed reduction potentials in the range of −0.9 to −1.4 V.

Fiber level catalyst‐free oxidative carboxylation enhances physical properties of wood polymer composites

Polymer Composites, EarlyView.
From fiber modification to composite panels. Abstract The widespread use of environmentally friendly medium‐density fiberboard (MDF) panels as a wood composites is driven by their versatility, affordability, and durability. However, reliance on traditional wood preservatives and modifications raises significant environmental, health, and cost concerns ...
