Front Cover: S‐(Trifluoromethyl)Benzothioate (TFBT): A KF‐Based Reagent for Nucleophilic Trifluoromethylthiolation (Chem. Eur. J. 13/2022)

From inorganic fluoride to organic fluoride: Just as the old Chinese legend that a carp succeed in leaping over the divine gate will become a Chinese dragon. In the presence of 18‐c‐6, KF succeed in reacting with thiophosgene, leaping over obstacles of unstable SCF3 anion intermediate, and is being transformed into trifluoromethylthiolation reagent TFBT, which has been used in trifluoromethylthiolation of a variety of substrates including alkynes, halogenated hydrocarbons, alcohols, boronic acids, etc. More information can be found in the Research Article by J. Hu et al. (DOI: 10.1002/chem.202104395).
