Reactions of the hexafluoropropene (HFP) trimers — perfluoro-3-isopropyl- 4-methyl-2-pentene (I) and perfluoro-3-isopropyl-2-methyl-2-pentene (II) with thiols have been studied. Trimer (I) was shown to give vinyl derivatives by substitution of fluorine atoms. Interaction of trimer (II) with thiols produces alkyl(aryl)perfluoroalkadienylsulfides. A mechanism for their formation, including nucleophilic attack of the thiolate-anion at a RS-group of intermediate alkyl(aryl)perfluoroalkenylsulfides is proposed. The first perfluoroalkylsubstituted thiete is obtained.

六氟丙烯三聚体与硫醇的反应

研究了六氟丙烯（HFP）三聚体-全氟-3-异丙基-4-甲基-2-戊烯（I）和全氟-3-异丙基-2-甲基-2-戊烯（II）与硫醇的反应。显示三聚体（I）通过取代氟原子得到乙烯基衍生物。三聚体（II）与硫醇的相互作用产生烷基（芳基）全氟链二烯基硫。提出了它们的形成机理，包括硫醇根阴离子在中间体烷基（芳基）全氟烯基硫化物的RS-基团处的亲核攻击。获得第一全氟烷基取代的硫杂环丁烷。
