Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Simultaneous Degradation, Dehalogenation, and Detoxification of Halogenated Antibiotics by Carbon Dioxide Radical Anions

Engineering
Despite the extensive application of advanced oxidation processes (AOPs) in water treatment, the efficiency of AOPs in eliminating various emerging contaminants such as halogenated antibiotics is constrained by a number of factors.

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

Chemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

The BhbA Enzyme Assay

Bio-Protocol, 2014
Reductive dehalogenation has been found primarily in anaerobic communities and is originally thought to rarely occur in aerobes. A reductive dehalogenase (BhbA) was characterized from an aerobic strain of Comamonas sp.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Late‐Stage Modification of Halotryptophan‐Containing Peptides Via Negishi Cross‐Coupling

Chemistry – A European Journal, EarlyView.
Negishi cross‐coupling provides access to the late‐stage functionalization of bromotryptophan‐containing peptides under comparatively mild conditions and is applicable to a range of peptide substrates in the investigated model systems. The examined alkyl iodides and variation of N‐terminal residues demonstrate the feasibility of the transformation in a
