A simple and robust method for electrochemical alkyl C–H fluorination is presented. Using a simple nitrate additive, a widely available fluorine source (Selectfluor), and carbon-based electrodes, a wide variety of activated and unactivated C–H bonds are converted into their C–F congeners. The scalability of the reaction is also demonstrated with a 100 gram preparation of fluorovaline.

The mechanochemical fluorination of unactivatedC(sp3)−H bonds has been achieved using N-fluorobenzenesulfonimide as both a precursor of the hydrogen-atom-transfer reagent and a bench-stable fluorine source. The control experiments revealed that mechanical energy is essential for realizing this reaction.
