Cellulose Acetates in Hydrothermal Carbonization: A Green Pathway to Valorize Residual Bioplastics

ChemSusChem, Volume 18, Issue 2, January 14, 2025.
Pure and commercial cellulose acetates are subjected to hydrothermal carbonization as a possible end‐of‐life strategy. The plasticizers cause the material to completely dissolve in the liquid phase at 190 °C. Valuable carbonaceous solids and platform chemicals were observed in the products, proving the possibility of applying this approach in a ...

Visible Light Promoted Site‐Specific Functionalization of α‐Acyloxy Carboxamides: Unlocking a Forbidden Chemical Space in the Passerini Reaction

Chemistry – A European Journal, Volume 30, Issue 50, September 5, 2024.
A novel method is presented, demonstrating the facile generation of α‐acyloxy carboxamide radicals via photoredox catalysis of Passerini adducts, obtained employing a 4‐formyl‐1,4‐dihydropyridine. These radicals efficiently undergo Giese reactions with various olefins, yielding novel Passerini compounds unattainable through traditional aldehyde‐based ...

Insights into the molecular mechanism of dehalogenation catalyzed by D-2-haloacid dehalogenase from crystal structures

, 2018
D-2-haloacid dehalogenases (D-DEXs) catalyse the hydrolytic dehalogenation of D-2-haloacids, releasing halide ions and producing the corresponding 2-hydroxyacids.

Anaerobic defluorination of chlorine-substituted per- and polyfluorinated carboxylic acids triggered by microbial dechlorination

, 2022
Chlorinated per- and polyfluoroalkyl substances (Cl-PFAS) have been manufactured and widely used in industrial and commercial products. Here, we report on significant anaerobic biodefluorinaiton structures and novel defluorination pathways of specific Cl-

Toxicity of Dietary Exposure to 3‐Monochloropropanediol, Glycidol, and Their Fatty Acid Esters

Journal of Food Quality, Volume 2024, Issue 1, 2024.
3‐Monochloropropane‐1,2‐diol (3‐MCPD), 2,3‐epoxy‐1‐propanol (glycidol), and their fatty acid esters are heat‐induced food toxicants that have widely been investigated. This review study presents an overview of current knowledge about the dietary toxicity of 3‐MCPD, glycidol, and their fatty acid esters. A literature search in two databases from January

Interactions of non-natural halogenated substrates with D-specific dehalogenase (DehD) mutants using in silico studies [PDF]

, 2014
The D-2-haloacid dehalogenase of D-specific dehalogenase (DehD) from Rhizobium sp. RC1 catalyses the hydrolytic dehalogenation of D-haloalkanoic acids, inverting the substrate-product configuration and thereby forming the corresponding L-hydroxyalkanoic ...

Dehalogenation of Haloalkanes by Mycobacterium tuberculosis H37Rv and Other Mycobacteria

, 2020
Haloalkane dehalogenases convert haloalkanes to their corresponding alcohols by a hydrolytic mechanism. To date, various haloalkane dehalogenases have been isolated from bacteria colonizing environments that are contaminated with halogenated compounds. A
