The preparation of the first ortho-substituted pentafluorosulfanylbenzenes was achieved. Oxidative fluorination (AgF2) of a series of aromatic disulfides containing different substituents ortho to the disulfide moiety gave only one ortho-substituted SF5-benzene, namely 1-fluoro-4-nitro-2-pentafluorosulfanylbenzene. This compound has been transformed into a variety of other ortho-substituted SF5-benzenes

diaryl disulfides occurs through the S—S bond cleavage to form dihalo-, halonitro-, and halodinitrophenyl perfluoroalkyl sulfides. The latter type of compounds was obtained for the first time. The main side process is the perfluoroalkylation of the aromatic ring.
在二芳基二硫化物存在下,氙 (ii) 双(全氟烷烃羧酸盐)的热解通过 SS 键断裂发生,形成二卤代-、卤代硝基-和卤代二硝基苯基全氟烷基硫化物。后一类化合物是首次获得。主要的副过程是芳环的全氟烷基化。
