Abstract
The combination of triflic anhydride and potassium iodide was an effective promoter for the deoxygenation of sulfoxides and gave the corresponding sulfides in excellent yield in acetonitrile at room temperature. This reagent system is chemoselective and tolerates various functional groups, such as alkenes, ketones, esters, aldehydes, acids, and oximes.
