Reactions of 1,1-dichloropolyfluoroalkanesulfenyl chlorides with ammonia afford 1,1-dichloropolyfluoroalkanesulfenamides that under the action of triethylamine are converted into 3,5-bispolyfluoroalkyl-1,2,4-thiadiazoles.

Abstract A new efficient method for the preparation of 2‐polyfluoroalkyl substituted 1,4,5,6‐tetrahydropyrimidines and 4,5,6,7‐tetrahydro‐1H‐1,3‐diazepines by the reaction of polyfluoroalkanethiocarboxylic acids amides and 1,3‐propylenediamine or 1,4‐buthylenediamine is presented.
