A route to α hydropolyfluoroalkanethiols and polyfluorothioacyl halides via thermal split ting of benzyl polyfluoroalkyl sulfides under the action of phosphorus pentoxide was proposed. The thiols obtained were used as starting materials for the synthesis of α hydropoly fluoroalkanesulfenyl chlorides. The properties of the resulting F,S containing compounds were studied.

The reactions of dibasic carbon acids such as (II), (V) and (VIII) with the perfluoroacyl chlorides (I) in the presence of NEt3 according to method A) afford the stable enolates (III), (VI) and (IX).
