The present invention relates to a process for the preparation of perhaloalkylthioethers by bringing a perhaloalkyl halide, preferably a bromide or an iodide, into contact with a disulphide in the presence of zinc and of sulphur dioxide or of a dithionite or of a hydroxymethanesulphinate or of a formate anion and sulphur dioxide.

Reaction of zinc and bromotrifluoromethane, or perfluoroalkyl-iodides, with thiocyanates and isoyanates gives respectively trifluoromethylsulfides and substituted trifluoroacetamides, as well as their long chain analogs.

Perfluorothioalkanoyl halides were generated from alkyl perfluoroalkyl sulfides by reaction with TiF4, TiCl4 or ClS03H. The alkyl groups were benzyl or methyl, the former was more suitable. An α-bromoperfluoroalkyl-sulfide gave a perfluorothioalkanoyl halide more easily than the corresponding α-chloro sulfide which gave the thioalkanoyl chloride.

通过与TiF 4,TiCl 4或ClSO 3 H反应,由烷基全氟烷基硫化物生成全氟硫代烷酰卤。烷基为苄基或甲基,前者更合适。与产生硫代链烷酰氯的相应α-氯硫化物相比,α-溴全氟烷基硫化物更容易得到全氟硫代链烷酰卤。硫化物R F CFXSR H(X = Cl,Br)的α卤素原子X与路易斯酸的卤素原子之间可能发生交换。
