Few-Atomic Zero-Valent Palladium Ensembles for Efficient Reductive Dehydrogenation and Dehalogenation Catalysis.

ACS Nano, 2023
Single-atom catalysts (SACs) offer immense potential in heterogeneous catalysis due to their maximized atomic utilization and high selectivity but suffer the problem of low reactivity in catalytic reductive reactions due to their high-valent state. Here,

Waste activated sludge stimulates in situ microbial reductive dehalogenation of organohalide-contaminated soil.

Journal of Hazardous Materials, 2021
Due to its enriched organic matter, nutrients and growth cofactors, as well as a diverse range of microorganisms, waste activated sludge (WAS) might be an ideal additive to stimulate organohalide respiration for in situ bioremediation of organohalide ...

Complete biodegradation of tetrabromobisphenol A through sequential anaerobic reductive dehalogenation and aerobic oxidation

Journal of Hazardous Materials
Tetrabromobisphenol A (TBBPA), a common brominated flame retardant and a notorious pollutant in anaerobic environments, resists aerobic degradation but can undergo reductive dehalogenation to produce bisphenol A (BPA), an endocrine disruptor. Conversely,

Reductive Dehalogenation – Challenges of Perfluorinated Organics

Journal of Photocatalysis, 2021
: In this mini-review, the problem of effective elimination of perfluorinated organic micropollutants from aquatic environment has been touched. The extraordinary chemical stability of common perfluorinated organic surfactants results in unsatisfactory efficiency of conventional treatment processes, which opens perspectives for photocatalytic methods -

The stereochemistry of reductive dehalogenation

Tetrahedron, 1968
Abstract The stereochemistry of reductive dehalogenation has been examined employing three representative reducing agents—zinc and acetic acid, chromous acetate, and catalytic hydrogenation over Pd C. Chromous acetate and zinc and acetic acid reduce, in greater than 70% yield, just the chlorine atom anti to the double bond in the title compound ...

Electrochemical reductive dehalogenation of chlorobenzenes

Russian Chemical Bulletin, 1995
Electrochemical dechlorination of 1,2,3,5-tetrachlorobenzene in methanol and chlorobenzene in dimethylsulfoxide with tetraalkylammonium salts as supporting electrolytes was carried out. The extent of dechlorination depends significantly on the electrode composition.

Reductive dehalogenation and dehalogenative sulfonation of phenols and heteroaromatics with sodium sulfite in an aqueous medium

Green Chemistry, 2019
Prototropic tautomerism was used as a tool for the reductive dehalogenation of (hetero)aryl bromides and iodides, or dehalogenative sulfonation of (hetero)aryl chlorides and fluorides, using sodium sulfite as the sole reagent in an aqueous medium.
