Bench‐Stable Electrophilic Reagents for the Direct Di‐ and Trifluoroethylthiolation of Indoles
Advanced Synthesis &Catalysis, Volume 365, Issue 20, Page 3438-3443, October 24, 2023., 2023 Abstract Two saccharine‐based electrophilic reagents were developed for the direct introduction of SCH2CF3 and SCH2CF2H motifs via a C−S bond forming reaction. Their large‐scale preparation and reactivity performance has been carefully examined, enabling access to a series of indoles through open‐flask reactions.

The 2021 European Union report on pesticide residues in food
EFSA Journal, Volume 21, Issue 4, April 2023., 2023 Abstract Under European Union legislation (Article 32, Regulation (EC) No 396/2005), EFSA is to provide an annual report assessing the pesticide residue levels in foods on the European market. In 2021, 96.1% of the overall 87,863 samples analysed fell below the maximum residue level (MRL), 3.9% exceeded this level, of which 2.5% were non‐compliant, i.e.
