Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness [PDF]

ChemSusChem
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.

Stabilization of Pd Active Sites by Defective NaY Zeolite Framework for Enhanced Stability in Dimethyl Carbonate Synthesis

EcoEnergy, EarlyView.
A tailored‐defect strategy employing sequential high‐temperature calcination and acetylacetone treatment was developed to generate framework defects in NaY zeolite while preventing the formation of strong acid sites. These defects facilitate electron transfer from Pd to the zeolite framework and stabilize the Pd2+ active sites, thereby conferring ...

Chemoselectivity and Enantioselectivity in the Conjugate Reduction of Cinnamate Esters and a Tandem Conjugate Reduction‐Ester Hydrogenation Using Manganese Catalysts

European Journal of Organic Chemistry, EarlyView.
An improved synthesis of a manganese catalyst used for hydrogenation of ketones, esters and imines is reported. The catalyst has now been found to effect tandem conjugate reduction‐ester hydrogenations with very low amounts of allylic alcohol by‐products.
