✦ Synopsis

Treatment of N,N-dichloroperfluoroalkanesulfonylamines with sulfur powder at room temperature gave the title products R f SO 2 N‫ס‬SCl 2 in good yields. They reacted readily with dimethyl sulfoxide, chloral, DMF, benzophenone, and similar compounds to form to corresponding imines R f SO 2 N‫ס‬YR 1 R 2 (Y: S, C). A reaction mechanism, one involving formation of a four-membered intermediate, is proposed. ᭧ 1999
