WebUsing an approach that combined classical enrichment protocols in a defined sediment-free medium with genetic screening of the microbial commu-nities, two anaerobic PCB-dechlorinating microorgan-isms, o -17 and DF-1, both distantly related to Dehalococ-[Drinker et al., 1937], PCBs continued to be used for de-cades. The dechlorinating bacteria use this H 2 as their electron donor, ultimately replacing chlorine atoms in the chloroethenes with hydrogen atoms via hydrogenolytic reductive dechlorination. This process can proceed in the soil provided the availability of organic electron donors and the … See more In organochlorine chemistry, reductive dechlorination describes any chemical reaction which cleaves the covalent bond between carbon and chlorine via reductants, to release chloride ions. Many modalities have been … See more Dechlorination is a common reaction in organic synthesis. Usually only stoichiometric amounts of dechlorinating agent are used. A classic Ullmann reaction is the conversion of 2-chloronitrobenzene into 2,2'-dinitrobiphenyl with a copper - bronze See more Vicinal reduction involves the removal of two halogen atoms that are adjacent on the same alkane or alkene, leading to the formation of an additional carbon-carbon bond.
