Highly chemoselective synthesis of aryl allylic sulfoxides through calcium hypobromite oxidation of aryl allylic sulfides

A highly chemoselective oxidation of widely substituted aryl allylic sulfides, prepared by allylation of arylthioethers with KF-Celite, to the corresponding aryl allylic sulfoxide was achieved by employing calcium hypobromite. Neither over-oxidation to sulfones nor halogenation of the aromatic rings was observed. The protocol may be successfully applied for the oxidation of substituted allylic systems (i.e., 2-haloallyl) that per se could interact with the oxidizing agent.
Efficient and selective sulfoxidation by hydrogen peroxide, using a recyclable flavin-[BMIm]PF6 catalytic system
Linden, Auri A.,Johansson, Mikael,Hermanns, Nina,Baeckvall, Jan-E.

A new flavin catalyst 2 immobilized in an ionic liquid ([BMIm]PF 6) was used for the highly selective oxidation of sulfides to sulfoxides by hydrogen peroxide. The sulfoxides were obtained in good to high yields and high selectivity without any
Mild and highly chemoselective oxidation of thioethers mediated by Sc(OTf)3
Matteucci, Mizio,Bhalay, Gurdip,Bradley, Mark
, p. 235 - 237 (2007/10/03)
(Matrix presented) Catalytic Sc(OTf)3 greatly increases the efficiency of hydrogen peroxide mediated monooxidation of alkyl-aryl sulfides and methyl cysteine containing peptides. The method is high yielding, compatible with many widely used protecting groups, suitable for solid-phase applications and proceeds with minimum over-oxidation.
