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.
3-氨基-4-R-呋喃嗪可以通过在液相和固相条件下用氟-氩混合物氟化而转化为相应的3-二氟氨基-4-R-呋喃嗪。在给电子和吸电子取代基 R 存在的情况下可以发生氟化;一些取代基R在氟化条件下发生转变。
