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.
Cyclobutanols and cyclopropanols underwent ring-opening fluorination upon treatment with Selectfluor in the presence of a substoichiometric amount of a silver salt. The reaction provides an efficient method to synthesize γ- and β-fluoroalkyl ketones.
