Synthetic Lignin Oligomers: Analytical Techniques, Challenges, and Opportunities
ChemSusChem, Volume 18, Issue 10, May 19, 2025.The review begins by discussing lignin and its structural complexity, followed by challenges in elucidating depolymerization products and the analytical techniques used. It then focuses on the chemical structure of synthetic lignin oligomers, their synthesis mechanisms, and their significance in current science. Finally, scientific gaps are identified,

Sustainable Synthesis of 1,2,3‐Triazoles using Cyrene as a Biodegradable Solvent in Click Chemistry
ChemSusChem, Volume 18, Issue 10, May 19, 2025.Green triazoles: The first successful synthesis of 1,2,3‐triazoles using Cyrene as a biodegradable and non‐toxic solvent in click chemistry has been developed. This sustainable approach allows product isolation by simple precipitation in water, eliminating the need for organic solvent extractions and chromatographic purifications, thus minimizing waste

Advanced Synthesis &Catalysis, Volume 367, Issue 9, May 6, 2025.Abstract A strategy for the immobilization of Johnston's Mono(AMidine) catalyst (MAM) onto polystyrene, silica and hybrid silica‐polystyrene nanoparticles is presented. The catalyst activity was evaluated in the stereoselective aza‐Henry reaction leading to the pivotal β‐amino nitroalkane precursors of the anti‐cancer agents Nutlins (with Nutlin‐3a as ...

One‐Pot Depolymerization of Mixed Plastics Using a Dual Enzyme System
ChemSusChem, Volume 18, Issue 9, May 5, 2025.The concurrent depolymerization of a polymer blend comprising three hydrolyzable plastics is demonstrated by employing an esterase and a urethanase in a sequential one‐pot process. The reaction resulted in a depolymerization degree of around 40 %, which corresponds to a minimum monomer yield of 3 % for 4,4′‐methylenedianiline (MDA) and a maximum of 55 %
