Reductive catalytic dehalogenation of light chlorocarbons

, 1999
Several palladium and platinum supported catalysts have been employed in the gas-phase dehalogenation of chloromethanes (CCl4, CHCl3 and CH2Cl2) and chlorobenzene by using molecular hydrogen under mild conditions.

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

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate

Chemistry – A European Journal, EarlyView.
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Thermochemical Factors Affecting the Dehalogenation of Aromatics

, 2016
Halogenated aromatics are one of the largest chemical classes of environmental contaminants, and dehalogenation remains one of the most important processes by which these compounds are degraded and detoxified.

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

Extracellularly Activatable Conjugates of RGD Peptidomimetics and Cryptophycin for αVβ3‐Targeted Cancer Therapy

Chemistry – A European Journal, EarlyView.
Integrin αVβ3‐targeting small‐molecule drug conjugates (SMDCs) were synthesized by conjugating a cryptophycin payload through a neutrophil elastase‐cleavable NPV‐PABC linker. RGD peptidomimetic and linker epimers served as controls for targeting and enzymatic cleavage, and the resulting conjugates displayed subnanomolar cytotoxicity in vitro.

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

, 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 ...

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.
