Synthesis and reactivity of fluorine-containing thiols and thioacyl halides
A route to α-hydropolyfluoroalkanethiols and polyfluorothioacyl halides via thermal splitting 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-hydropolyfluoroalkanesulfenyl chlorides. The properties of the resulting F,S-containing compounds were studied.

A method has been found for the synthesis of fluoride-containing α-hydrothionyl fluorides by heating polyfluoroalkenyl benzyl sulfides having fluoride atoms in the α-position relative to the sulfur atom with fluorosulfonic acid.The reactions of the acid fluorides obtained with secondary amines were studied.The reaction of the α-hydrotetrafluorothiopropionyl fluoride with NH(Me)2 leads to the amide of the corresponding acid, while the product of α-hydrohexafluorothioisobutyryl fluoride with diethylamine is the dimer of bis(trifluoromethyl)thioketene.
