Carbonylative Suzuki–Miyaura Coupling of 1‐Iodoglycals Mediated by the N‐Heterocyclic Carbene Catalyst PEPPSI: Preparation of C‐Acyl Glycosides

European Journal of Organic Chemistry, Volume 29, Issue 7, 23 February 2026.
A multicomponent carbonylative Suzuki–Miyaura reaction was developed for the synthesis of C‐acyl glycosides. Using Pyridine‐Enhanced Precatalyst Preparation, Stabilization, and Initiation (PEPPSI‐IPr) catalysis and Mo(CO)6 as a solid CO source, the reaction enables selective carbonylation of three components in synthetically useful yields, providing a ...

Soil microbes in the Tibetan Plateau degrade polyvinyl chloride and harbor novel dehalogenase SerB

Environment International
Polyvinyl chloride (PVC) stands as the third most widely produced synthetic polymer plastic. However, investigations into its microbial degradation significantly trail those of polyethylene (PE) and polystyrene (PS).

Haloalkalitolerant Nitrile‐Utilizing Rhodococcus Strains Promote the Biodegradation of Nitrile‐Butadiene Rubber

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Environmental pollution from polymers is reaching alarming levels. Nitrile‐butadiene rubber (NBR), widely used in medical glove manufacturing, contributes significantly to plastic and microplastic pollution. Nitrile gloves have become a major component of COVID‐19 pandemic‐related waste. In this study, we demonstrated the ability of haloalkalitolerant,

Reaction Mechanism of DL-2-Haloacid Dehalogenase from Pseudomonas sp. 113: Hydrolytic Dehalogenation Not Involving Enzyme-Substrate Ester Intermediate (MOLECULAR BIOFUNCTION-Molecular Microbial Science) [PDF]

, 2000
DL-2-Haloacid dehalogenase from Pseudomonas sp. 113 (DL-DEX 113) catalyzes the hydrolytic dehalogenation of D- and L-2-haloalkanoic acids, producing the corresponding L- and D-2- hydroxyalkanoic acids, respectively.

Dehalogenation of Haloalkanes by Mycobacterium tuberculosis H37Rv and Other Mycobacteria [PDF]

, 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

Bioinspired Design of Heterogenous Single‐Atomic‐Site Catalysts for Electrocatalysis and Photocatalysis

Advanced Materials, Volume 37, Issue 48, December 3, 2025.
This review gives a summary on the representative bioinspired single‐atomic‐site catalysts (SACs) and their applications in heterogeneous electrocatalysis and photocatalysis. The fundamentals of bioinspired design strategies are systematically discussed in the context of the first shell coordination, the second/long‐range coordination, and the outer ...

Crystal Structures of Intermediates in the Dehalogenation of Haloalkanoates by L-2-Haloacid Dehalogenase [PDF]

, 1999
The L-2-haloacid dehalogenase from the 1,2-dichloroethane-degrading bacterium Xanthobacter autotrophicus GJ10 catalyzes the hydrolytic dehalogenation of small L-2-haloalkanoates to their corresponding D-2-hydroxyalkanoates, with inversion of the ...

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 ...
