A mild, selective, and high-yielding method for oxidation of sulfides to sulfoxides using IBX and tetraethylammonium bromide in a variety of solvents is described. The method offers the advantage of short reaction times, no over-oxidation to sulfones, and compatibility to a wide range of functional groups.

The article describes the use of iodic acid in combination with catalytic amounts of tetraethylammonium bromide (TEAB) as a mild and alternative reagent system for oxidation of sulfides to sulfoxides. The salient features of the developed system are room-temperature reactions, short reaction times, and compatibility with a wide range of functional groups.
