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.

The stepwise nucleophilic addition of 2-mercaptoethanol (2) to 1-fluoroalkyl-2-iodo-alkenes (1) was studied. Fluorine-containing building blocks of a new type (4) containing a fluorine atom, a fluoroalkyl-substituted double bond and a latent carbonyl group were synthesized in good yield via the intermediate thioethers 3. A reasonable pathway is suggested. (C) 1997 Elsevier Science S.A.
