Bromate in drinking water a problem in Switzerland?

Ozonation of bromide-containing waters causes the formation of bromate which is considered to be potentially carcinogenic. An investigation in Switzerland on water works using ozone (85) has shown that the new drinking water standard of 10 mug/L for ...

Synthesis of Tris(indol‐3‐yl)methanes From Indoles, CO2, and Dimethylphenylsilane With BPh3: Two‐Step Construction of π‐Conjugated Systems

Chemistry – A European Journal, EarlyView.
Tris(indol‐3‐yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. One product, tris(4‐bromo‐1‐methylindol‐3‐yl)methane, underwent a palladium‐catalyzed cascade reaction for the formation of a novel polycyclic heteroaromatic compound, where the methine C(sp3) atom originating from CO2 was ...

Options and limitations for bromate control during ozonation of wastewater

Wastewater treatment plants (WWTPs) are important point sources for micropollutants, which are harmful to freshwater organisms. Ozonation of wastewater is a powerful option to abate micropollutants, but may result in the formation of the potentially ...

From Charge‐Transfer Adducts to (Tri)Halide‐Templated Supramolecular Cages: Covalent vs Ionic Products in the Reactions of Pyridin‐4‐ylthio‐Substituted Tetrathiafulvalene With Dihalogens and Interhalogens

Chemistry – A European Journal, EarlyView.
The reactions between tetra(pyridin‐4‐ylthio)tetrathiafulvalene and Br2/I2/ICl/IBr led to a variety of products, including a rare example of neutral 1:4 CT adduct and ionic products showing supramolecular cage motifs at (tri)halide templates. The nature of the reaction products was elucidated based on XRD analysis, Raman spectroscopy and QTAIM, NCI ...

Factors and mechanisms controlling bromate removal by zerovalent iron

, 2005
The zerovalent iron (Fe(0)) technology widely used in remediating contaminated groundwater can be applied to drinking water treatment for reduction of bromate, a refractory by-product produced during ozone disinfection.

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

β‐Ketonitrile‐Modified Prodan Derivatives as Large‐Stokes‐Shift Solvatochromic Fluorophores With Enhanced Brightness and Ratiometric Thermometric Response

Chemistry – A European Journal, EarlyView.
We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.
