A Hoveyda–Grubbs‐Type Olefin Metathesis Catalyst Bearing a Fluorinated Unsymmetrical NHC Ligand
European Journal of Inorganic Chemistry, EarlyView.A fluorinated unsymmetrical NHC ruthenium complex was synthesised and employed as a catalyst for olefin metathesis reactions. The modification of the steric and electronic properties of the NHC ligand through the introduction of fluorine substituents results in improved activity but lower selectivity compared to the analogous non‐fluorinated NHC ...

European Journal of Organic Chemistry, EarlyView.A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Food Safety and Health, EarlyView.This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.
