Cobamide-mediated enzymatic reductive dehalogenation via long-range electron transfer

Nature Communications, 2017
Cobalamin-containing reductive dehalogenases from organohalide-respiring bacteria play a key role in the degradation of halogenated organic compounds. Here the authors proposed a catalytic mechanism for dehalogenation that relies on a long-range electron

Anaerobic reductive dehalogenation of trichloroethylene in unacclimated freshwater sediments

, 2001
Currently, “halorespiration” dominates the environmental engineering and microbiological literature as an explanation for the occurrence of microbially mediated reductive dehalogenation in the environment.

Co7-cluster metal–organic frameworks for photocatalytic dehalogenation reduction

Polyoxometalates
Photocatalytic dehalogenation reduction, which converts a C–X bond into a C–H bond, plays a significant role in synthetic catalysis and pollutant remediation.

Catalytic reductive dehalogenation of hexachloroethane by molecular variants of cytochrome P450cam (CYP101).

, 2000
CYP101 (cytochrome P450cam) catalyses the oxidation of camphor but has also been shown to catalyse the reductive dehalogenation of hexachloroethane and pentachloroethane.

A Role for Dehalobacter spp. in the Reductive Dehalogenation of Dichlorobenzenes and Monochlorobenzene

, 2016
Previously, we demonstrated the reductive dehalogenation of dichlorobenzene (DCB) isomers to monochlorobenzene (MCB), and MCB to benzene in sediment microcosms derived from a chlorobenzene-contaminated site.

Combined C and Cl Isotope Effects Indicate Differences between Corrinoids and Enzyme (Sulfurospirillum multivorans PceA) in Reductive Dehalogenation of Tetrachloroethene, But Not Trichloroethene

, 2016
The role of the corrinoid cofactor in reductive dehalogenation catalysis by tetrachloroethene reductive dehalogenase (PceA) of Sulfurospirillum multivorans was investigated using isotope analysis of carbon and chlorine.

A Catalytic Borylation/Dehalogenation Route to o‑Fluoro Arylboronates

, 2015
A two-step Ir-catalyzed borylation/Pd-catalyzed dehalogenation sequence allows for the net synthesis of fluoroarenes where the boronic ester is ortho to fluorine.

Viologen-mediated reductive dehalogenation of α-halogeno ketones

, 2018
Various α-halogeno ketones undergo reductive dehalogenation to the corresponding ketones almost quantitatively with sodium dithionite using viologen as an electron-transfer catalyst in organic solvent-water two-phase ...

, 2014
The role of the corrinoid cofactor in reductive dehalogenation catalysis by tetrachloroethene reductive dehalogenase (PceA) of Sulfurospirillum multivorans was investigated using isotope analysis of carbon and chlorine.

Competing Dehalogenation versus Borylation of Aryl Iodides and Bromides under Transition-Metal-Free Basic Conditions

, 2019
In this work, selectivity-controllable base-promoted transition-metal-free borylation and dehalogenation of aryl halides are described. Under the conditions of borylation, the dehalogenation which emerges as a competitive side reaction has been well ...
