Learning from B12 enzymes: biomimetic and bioinspired catalysts for eco-friendly organic synthesis

Beilstein Journal of Organic Chemistry, 2018
Cobalamins (B12) play various important roles in vivo. Most B12-dependent enzymes are divided into three main subfamilies: adenosylcobalamin-dependent isomerases, methylcobalamin-dependent methyltransferases, and dehalogenases. Mimicking these B12 enzyme

Reductive dehalogenation as a respiratory process [PDF]

Antonie van Leeuwenhoek, 1994
Anaerobic bacteria can reductively dehalogenate aliphatic and aromatic halogenated compounds in a respiratory process. Only a few of these bacteria have been isolated in pure cultures. However, long acclimation periods, substrate specificity, high dehalogenation rates, and the possibility to enrich for the dehalogenation activity by subcultivation in ...

Pyridine‐2‐Sulfinate as a Bifunctional SO2 Transfer Reagent; Unlocking Structurally Diverse, Ortho‐Functionalized Masked Sulfinates

Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
The commercially available 2‐pyridyl “Willis’ sulfinate” is demonstrated as an efficient SO2 transfer reagent (STR) providing single‐step access to a 2‐pyridyl masked sulfinate from (hetero)aryl bromides and iodides. Following installation, the pyridyl auxiliary delivers ortho‐selective functionalization via chelate‐assisted CH activation, providing a ...

The effect of sulfide on the reductive dehalogenation of tetrachloroethylene

, 1999
One of the potential variables that appears to play a major role in the development and dehalogenation ability of bacterial cultures is the external reductant employed in the research to reduce the liquid anaerobic medium. In this research, the effect of

Fungal Strains as Catalysts for the Biotransformation of Halolactones by Hydrolytic Dehalogenation with the Dimethylcyclohexane System

Molecules, 2012
Bicyclic chloro-, bromo- and iodo-γ-lactones with dimethylcyclohexane rings were used as substrates for bioconversion by several fungal strains (<em>Fusarium</em>, <em>Botrytis</em> and <em>Beauveria</em>). Most of the

Enabling Cross‐Coupling Reactivity of α‐Pentafluorosulfanyl Compounds with a Thermally Stable Organozinc α‐SF5 Reagent

Chemistry – A European Journal, Volume 32, Issue 41, 3 November 2026.
This work describes the first example of a thermally stable α‐SF5 organometallic reagent, which allows for extensive downstream functionalization by allylation and acylation reactions under copper catalysis, as well as palladium‐catalyzed Negishi‐type cross‐coupling conditions up to 96% yield. In silico analysis shines initial light on the requirements

Use of Polycyclic Aromatic Compounds as Electrophotocatalysts in Organic Reactions

Chemistry–Methods, Volume 6, Issue 11, November 2026.
Emerging from the convergence of photoredox catalysis and electrochemistry, electrophotocatalysis is a relatively new and promising synthetic approach in organic chemistry. In this review, the main advantages and the current challenges of this methodology are discussed, while most relevant and late applications of polycyclic aromatic hydrocarbons (PAHs)

Preparation of sub-microspherical Fe3O4@PDA-Pd NPs catalyst and application in catalytic hydroreduction reaction of halogenated aromatic nitro compounds to prepare halogenated aromatic amines

BMC Chemistry, 2019
Background The side reactions of dehalogenation or C–N coupling tend to occur when halogenated aromatic amines are prepared by catalytic hydrogenation reduction of halogenated aromatic nitro compounds.

Reactivity of Rh(I) Complexes Toward Fluorinated Ethers: Activation of Inhalation Anesthetics

ChemistryOpen, Volume 15, Issue 11, November 2026.
Reactions of the inhaled anesthetics and α‐fluorinated ethers sevoflurane, enflurane, and isoflurane with [Rh(H)(PEt3)3] led to versatile organometallic transformations including C(sp3)─F and C(sp3)─Cl bond cleavage and metal–halogen bond formation, a catalytic hydrodehalogenation reaction, as well as the generation of a unique fluorinated phosphonium ...

Regioselective alkali metal reduction of dibenzocyclooctadiene lignan derivatives, demethoxylation followed by dehalogenation

Chemistry Central Journal, 2017
The regioselective demethoxylation and dehalogenation of dihalogenated dibenzocyclooctadiene lignans derivatives were realized in a one-step reaction with excellent yields in the sodium and t-butanol reaction system.
