An oxidative variant of the thiol-ene reaction has been developed, achieving the direct addition of thiols to olefins to form sulfoxides. The reaction uses tert-butyl hydroperoxide as oxidant and methanesulfonic acid as catalyst. The latter is believed to catalyze the oxidation of the intermediate sulfide to the sulfoxide. No special precautions are necessary to exclude oxygen, yet the products are

Treatment of sulfoxides with trimethylsilyl iodide in the presence of sterically hindered tert-amines results in facile eliminative deoxygenation with the production of the corresponding vinyl sulfides.
