A novel method for the synthesis of 5-perfluoroalkyl-2,3-dihydro-1,4-diazepines using easily available starting materials is described. 1-Perfluoroalkyl-2-iodoethylenes, obtained from the reaction of perfluoroalkyl iodides and alkynes, reacted with ethylenediamine under mild conditions to give the title compounds in good yields. A possible mechanism is proposed.
