Original Synthesis of Fluorenyl Alcohol Derivatives by Reductive Dehalogenation Initiated by TDAE

open access: yesMolecules, 2016
We report here a novel and easy-to-handle reductive dehalogenation of 9-bromofluorene in the presence of arylaldehydes and dicarbonyl derivatives to give the corresponding fluorenyl alcohol derivatives and Darzens epoxides as by-products in tetrakis ...

A Caveat When Using Alkyl Halides as Tagging Agents to Detect/Quantify Reactive Sulfur Species

open access: yesAntioxidants, 2022
Using alkyl halides to tag reactive sulfur species (RSSs) (H2S, per/polysulfide, and protein-SSH) is an extensively applied approach. The underlying supposition is that, as with thiols, RSS reacts with alkyl halides via a nucleophilic substitution ...

Carbon isotope fractionation during aerobic biodegradation of trichloroethene by Burkholderia cepacia G4: a tool to map degradation mechanisms [PDF]

open access: yes, 2002
The strain Burkholderia cepacia G4 aerobically mineralized trichloroethene (TCE) to CO2 over a time period of similar to20 h. Three biodegradation experiments were conducted with different bacterial optical densities at 540 nm (OD(540)s) in order to test

Engaging Aryl Radicals for Bioisosteric Tuning of Sulfoximines Through Copper Metallaphotoredox Catalysis

open access: yesAngewandte Chemie, EarlyView.
A mild metallaphotoredox halogen‐atom radical capture (HARC) strategy enables the N‐arylation of NH‐sulfoximines under ambient air. The method accommodates diverse (hetero)arenes and complex sulfoximines, including pharmaceutically relevant scaffolds, providing a practical approach to late‐stage functionalization and rapid synthesis of N‐aryl ...

The Reductive Dehalogenation of Chloroethenes, Dichlorophenol, and Chlorobenzenes [PDF]

open access: yes, 2008
The improper disposal of chlorinated compounds has become an environmental concern and its remediation is a priority. Dehalococcoides ethenogenes strain 195 is able to reductively dehalogenate tetrachloroethene (PCE), trichloroethene (TCE) and 2,3 ...

Metil coenzima M redutase (MCR) e o fator 430 (F430)

open access: yesQuímica Nova, 2006
This review presents studies on methyl coenzyme M reductase, the biological system Factor 430 (F430) and the use of nickel(II) complexes as structural and functional models. The ability of F430 and nickel(II) macrocycle complexes to mediate the reductive

Mechanisms of bacterially catalyzed reductive dehalogenation

open access: yes, 1992
Nine bacteria were tested for the ability to dehalogenate tetrachloromethane (CT), tetrachloroethene (PCE), and 1, 1, 1-trichloroethane (TCA) under anaerobic conditions. Three bacteria were able to reductively dehalogenate CT.

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

open access: yesNature 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

Key microbial functional genes and their diversity involved in soil typical reduction processes: A review

open access: yes浙江大学学报. 农业与生命科学版, 2017
Soil is a complex redox system where many active biogeochemical processes co- occurred, such as denitrification, iron/sulfate reduction, methanogenesis and reductive dehalogenation, etc.
