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

Chemistry – A European Journal, EarlyView.
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

Dehalogenation of organic compounds by reductive radicals [PDF]

, 2010
-Radiolysis and measurements of halide ions by means of ion chromatography have been employed to investigate reductive dehalogenation of chloro-, bromo-, and iodophenols, halogenated aliphatic compounds and 5-bromouracil by carbon-centred radicals, •CH(CH3)OH, •CH2OH, and •CO2, in air-free aqueous solutions in the presence of ethanol, methanol or ...

Building Blocks for Acetylenic Scaffolding Inspired by 6,6,12‐Graphyne

European Journal of Organic Chemistry, EarlyView.
6,6,12‐Graphyne is an elusive allotrope of carbon. Here, we present the synthesis and properties of a selection of useful molecular building blocks to advance the preparation of various segments of 6,6,12‐graphyne. These modules are derived from tri‐ and tetraethynylethene derivatives, di‐ and tetraethynyl‐substituted tolane derivatives, as well as ...

Spatial Orientation‐Dependent Double Hydrogen Bond/Photoredox Cooperative Catalysis in Metal–Organic Frameworks

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
We report a heterogeneous double hydrogen bond/photoredox synergistic catalysis, wherein the flexibility and spatial orientation of catalytic centers, rather than catalyst activity, play a dominant role in catalytic performance. ABSTRACT Catalyst activity is typically the primary priority in designing a catalytic system. The higher catalyst activity is

Organohalide Respiring Bacteria and Reductive Dehalogenases: Key Tools in Organohalide Bioremediation

Frontiers in Microbiology, 2016
Organohalides are recalcitrant pollutants that have been responsible for substantial contamination of soils and groundwater. Organohalide-respiring bacteria (ORB) provide a potential solution to remediate contaminated sites, through their ability to use ...

Reductive dehalogenation of iopromide by zero-valent iron

Water Science and Technology, 2008
Iodinated X-ray contrast media (ICM), as derivatives of 2, 4, 6-triiodo benzoic acid, are applied in high doses to humans and are excreted unchanged via urine within 24 h. Common as well as advanced wastewater treatment is not able to remove the iodinated compounds leading to an environmental pollution.

Viruses in the sediments around the trenches harbor diverse survival mechanisms

iMetaOmics, EarlyView.
Deep‐sea trenches are the deepest and most isolated environments in the global ocean but the diversity and adaptation of the viral communities remain poorly characterized. In this study, 5563 viral operational taxonomic units (vOTUs) were identified from sediments of the Yap Trench and Western Caroline Basin.
