Abstract
A practical and efficient protocol for the switchable synthesis of sulfoxides, sulfones,
and thiosulfonates via Selectfluor-mediated oxidation of sulfides and thiols, respectively,
at ambient temperature has been developed. All these organosulfur compounds can be
prepared with nearly quantitative yields by applying eco-friendly H2O as O-source. The formation of sulfoxides and thiosulfonates takes only a few minutes
(3–20 min). As suggested by the control experiments, the oxidation procedure might
proceed through the fluorination of sulfide, nucleophilic addition with H2O, and elimination of hydrogen fluoride.
