The reaction of aromatic or benzylic disulfides with 2.5 equiv of Selectfluor in acetonitrile/water (10:1) at room temperature efficiently produced the corresponding thiosulfonates. Conversely, the reaction of disulfides with 6.5 equiv of Selectfluor or thiosulfonates with 4.5 equiv of Selectfluor in refluxing acetonitrile/water (10:1) provided sulfonyl fluorides in high yields. Accufluor and FP-T300 are also effective in preparing sulfonyl fluorides from disulfides under the similar reaction conditions. Sulfonyl chlorides or sulfonyl bromides were effectively obtained from the reaction of disulfides with 6 equiv of either N-chlorosuccinimide or N-bromosuccinimide in acetonitrile/water (10:1) at room temperature. Some other electrophilic chlorinating or brominating reagents are also able to be used instead of N-chlorosuccinimide or N-bromosuccinimide for the syntheses of sulfonyl halides from disulfides. These reactions of disulfides with electrophilic halogenating reagents are convenient methods to prepare thiosulfonates and sulfonyl halides.

The reaction of aromatic or benzylic disulfides with 2.5 equiv of Selectfluor in acetonitrile/water (10:1) at room temperature efficiently produced the corresponding thiosulfonates. On the other hand, the reaction of disulfides with 6.5 equiv of Selectfluor in refluxing acetonitrile/water (10:1) provided sulfonyl fluoride in high yields.
