Reductive Dehalogenation of Halogenated Aliphatic and Aromatic Organic Compounds with Metals.

open access: yes, 2007
The aim of this contribution is to supply information about the feasibility of reductive dehalogenation of selected pollutants (4-chlorophenol, PCB, PBDE, 1,2-dichloro ethane, vinylchloride) in synthetic and real waters on experiments in laboratory scale

Critical Role of Semiquinones in Reductive Dehalogenation

open access: yesEnvironmental Science & Technology, 2023
Quinones and products of their redox reactions (hydroquinones and semiquinones) have been suggested as important players in the reductive dehalogenation of organohalogens mediated by natural and pyrogenic organic matter, although based on limited direct evidence. This study focused on the reductive dehalogenation of a model organohalogen (triclosan) by

Biochemistry of Catabolic Reductive Dehalogenation

open access: yesAnnual Review of Biochemistry, 2017
A wide range of phylogenetically diverse microorganisms couple the reductive dehalogenation of organohalides to energy conservation. Key enzymes of such anaerobic catabolic pathways are corrinoid and Fe–S cluster–containing, membrane-associated reductive dehalogenases.

Anaerobic Reductive Dehalogenation of Polychlorinated Dioxins

Applied Microbiology and Biotechnology, 2009
Polychlorinated dibenzo-p-dioxins and -furans (PCDD/Fs) are among the most harmful environmental contaminants. Their widespread distribution due to unintentional or unknown release coincides with environmental persistence, acute and chronic toxicity to living organisms, and long-term effects due to the compounds' tendency for bioaccumulation and ...

Synergistic Effect in Bimetallic Ni–Al Clusters. Application to Efficient Catalytic Reductive Dehalogenation of Polychlorinated Arenes

open access: yesTetrahedron, 2000
International audienceSubnanometric Ni–Al clusters, in situ prepared by reduction of equimolar amounts of Ni(OAc)2 and Al(Acac)3 induced by alkoxide activated sodium hydride, exhibit a high catalytic activity for efficient reductive dehalogenation of ...

Mechanism of Cobalamin-Mediated Reductive Dehalogenation of Chloroethylenes [PDF]

open access: yesACS Catalysis, 2017
Reductive dehalogenation involvingcobalamin has been proved to be a promising strategy for decontamination of the polluted environment. However, cob(I)alamin can act both as a strong reductant and a powerful nucleophile, and thus, several competing ...

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 ...
