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. An exchangebetween the α-halogen atom X of the sulfide
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。
