3-Amino-4-R-furazans can be converted into the corresponding 3-difluoroamino-4-R-furazans by fluorination with a fluorine—argon mixture under both liquid-phase and solid-phase conditions. Fluorinations can be enabled in the presence of both electron-donating and electron-withdrawing substituents R; some substituents R underwent transformations under fluorination conditions.
