, p. 587 - 588 (1987)
Phenyl sulfoxides are easily prepared by the chemoselective oxidation of the corresponding sulfides with molecular equivalents of 2-hydroperoxy-2-methoxypropane.This reagent is generated from 2,3-dimethyl-2-butene by ozonization in methanol.
Selective oxidation of sulfides to sulfoxides using IBX-esters
Koposov, Alexey Y.,Zhdankin, Viktor V.
, p. 22 - 24 (2005)
IBX-esters (esters of 2-iodoxybenzoic acid) are convenient hypervalent iodine reagents for the clean and selective oxidation of organic sulfides to sulfoxides. This reaction proceeds without over-oxidation to sulfones and is compatible with the presence of the hydroxy group, double bond, phenol ether, benzylic carbon, and various substituted phenyl rings in the molecule of the substrate.

Self-assembly of polyoxometalates, transition metal salts, and 2,6-bis(2′-pyridyl)-4-hydroxypyridine (LOH) obtained four organic-inorganic hybrids [Co2.5(LOH)(LO)2(H2O)2(PW12O39)]·3CH3CN·2OH (1), [Zn1.5(LOH)3]·(PMo12O40)·CH3OH·2H2O (2), [Cd1.5(LOH)3]·(PW12O40)·2CH3OH·1.5H2O (3), and [Mn(LOH)2]·(PW12O40)·2CH3CN·H3O (4). Hybrid 1 exhibits an extended chain, which could be further connected into a 3D supramolecular architecture by H-bonds. Hybrids 2-4 feature monomolecular structures, which are further bridged via H-bonds to yield charming 3D supramolecular structures. Noteworthy, 1 and 2 can be employed as recyclable and highly efficient heterogeneous catalysts. The activated 1 displays a high catalytic activity for the cycloaddition reaction of CO2 and epoxides. Hybrid 2 exhibits an excellent catalytic performance for the oxidative desulfurization reaction.

Alkyl hydroperoxides derived from cyclohexanone are attractive oxidants because they are easily available, more reactive than TBHP but much less acidic than m-CPBA. Wherein 1,1′-peroxybis(1-hydroperoxycyclohexane) (C) can be generated by the current simply method and displays the excellent reactivity and selectivity based on oxidative reactions of various benzothiazolyl sulfides substituted by different function groups. The research found that the reactions can be performed in the absence of catalyst and under very mild conditions optimized. Yields of sulfoxides is higher than 90%, no or a little reaction happened at the proximal double bond、 N and S atoms in the benzothiazolyl moiety. Phenyl sulfide as the substrates was also examined for the reaction scope test. The results show that they were uniquely and completely oxidized to sulfoxides in 1 h. A mild, environmentally friendly, catalyst-free aryl sulfide sulfoxidation method has been developed.
