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 formed without oxidation at the β-position. Styrenes, acrylic acid derivatives, alkynes, and thiophenols gave the highest yields, while aliphatic olefins and thiols were less effective.

A surfactant based molybdenum system that exhibits catalytic activity for sulfoxidation reactions of various organic sulfides in aqueous medium has been developed and comprehensively characterized using IR, XRD, NMR, ESI-MS, DLS and TEM. The catalyst showcases remarkable selectivity for the preparation of both sulfoxides and sulfones in the range of good to excellent yields. Furthermore, the catalyst showed a high degree of tolerance towards various sensitive functional groups such as hydroxyl, acetal, aldehyde, amine, imine, oxime, cyano and alkene. the Partner Organisations 2014.

Brigaud, Thierry,Laurent, Andre,Laurent, Eliane
, p. 153 - 156 (2007/10/02)
Electrochemical oxidation of sulfides produces sulfonium ions.The reactivity of these ions versus fluoride anions is described.
Oxidative fluorination of sulfides in presence of Et3N.3HF
Brigaud,Laurent
, p. 2287 - 2290 (2007/10/02)
The synthesis of fluorocompounds by sulfide electrochemical oxidation using Et3N.3HF as fluorinating agent is described. Chemical oxidation (DBH) is less efficient.
