Potassium iodide
Recent Literature
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.
