Termination of Carbomethoxyethyl Radicals Generated by Br‐Atom Abstraction From MeCH(Br)COOMe With Metalloradicals: Implications for Polyacrylate Radical Termination

open access: yesChemistryEurope, Volume 4, Issue 6, June 2026.
Combination is the dominant bimolecular termination mode of the diffused acrylate radical carbomethoxyethyl (MeCH•(COOMe), or RH•), but its generation by Br‐atom abstraction from methyl 2‐bromopropionate (RH‐Br) with a variety of metalloradicals (Mt•) opens a competitive pathway via the {RH•, Mt•} caged pair, leading to 100% disproportionation ...

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

open access: yes, 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 ...

Halogen‐Bonding‐Induced Direct SET Activation of Aryl Iodides: Inorganic Bases as Self‐Sufficient Electron Donors

open access: yesChemPhotoChem, Volume 10, Issue 6, June 2026.
Simple inorganic bases emerge as potent photo‐reductants via halogen bonding without any exogenous organic additives. The formation of a discrete charge–transfer complex between aryl iodides and ubiquitous inorganic bases enables direct single‐electron transfer under mild LED irradiation, facilitating efficient access to aryl boronic esters, stannanes,

PFAS properties and destruction methods: A focus on enzymatic degradation

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 6, Page 1126-1152, June 2026.
Abstract Per‐ and polyfluoroalkyl substances (PFAS) are known as ‘forever’ chemicals and have lasting detrimental impact on the environment and living organisms. To understand PFAS molecules better, this review begins with an overview of PFAS definition, classifications and applications, and then provides a comprehensive summary and critical analysis ...

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Anaerobic reductive dehalogenation of trichloroethylene in unacclimated freshwater sediments

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

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
