Mild Transition-Metal-Free Amination of Fluoroarenes Catalyzed by Fluoride Ions

Trimethylsilyl-protected heterocycles undergo N−C bond formation with a variety of electron-deficient fluoroarenes catalyzed by fluoride ions. This reaction avoids stoichiometric amounts of base and thus makes <i>N</i>-arylheterocycles accessible in a very mild and transition-metal-free way.
