FLUORINE-CONTAINING α-HYDROTHIONYL FLUORIDES

Article abstract of DOI:10.1007/BF00961512

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.
