Sulfur dioxide, delivered from the surrogate DABSO, combines as electrophile with an organometallic reagent to generate a sulfinate intermediate. In situ conversion of the sulfinate to a sulfinate silyl ester, using TMS-Cl, generates another electrophile, allowing addition of a second organometallic reagent. Both organolithium or Grignard reagents deliver sulfoxides in very good yields.

The use of a chiral O,P-ligand (PC-Phos) enables an efficient palladium-catalyzed enantioselective arylation of both alkyl and aryl sulfenate anions to deliver various chiral sulfoxides in good yields with excellent enantioselectivities. The method offers general substrate scope and ease of scale-up.

A (JosiPhos)Pd-catalyzed reaction of aryl benzyl sulfoxides and aryl bromides provides chiral diaryl sulfoxides via an enantioselective arylation of aryl sulfenate anions. The method offers good functional group compatibility. A wide range of enantioenriched diaryl, aryl heteroaryl, and even diheteroaryl sulfoxides were generated.

A copper-catalyzed sulfinyl cross-coupling reaction of sulfinamides with aldehyde-derived N-tosylhydrazones provides structurally diverse sulfoxides. The reaction offers broad substrate scope and tolerates various functional groups. Moreover, the given sulfinyl cross-coupling reaction could be scaled up to the gram scale and carried out in a one-pot fashion directly from aldehydes.

A phenyltrimethylammonium tribromide-mediated nucleophilic substitution/oxygen transformation reaction of benzyl halides with DMSO enables a convenient and direct synthesis of various benzyl methyl sulfoxides. In this transition-metal-free reaction, DMSO acts as not only a solvent but also a "S(O)Me" source.

An oxidative variant of the thiol-ene reaction enables the direct addition of thiols to olefins to form sulfoxides in the presence of 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. Styrenes, acrylic acid derivatives, alkynes, and thiophenols gave the highest yields, while aliphatic olefins and thiols were less effective.

A visible light mediated sulfurization of alkenes and alkynes with aromatic and heteroaromatic thiols enables a benign and metal-free functionalization using Eosin Y as photocatalyst and eco-friendly air (O₂) as the sole oxidant. This selective approach shows good substrate generality to afford sulfoxides, β-hydroxysulfoxides, and β-keto sulfides in high yield.

A direct trideuteromethylation of sulfenate ions derived in situ from β-sulfinyl esters in the presence of a base utilizing inexpensive CD₃OTs as the electrophilic trideuteromethylating agent provides an array of trideuteromethyl sulfoxides in very good yields with a high degree of deuteration. Trideuteromethyl sulfoxides can be readily modified into trideuteromethyl sulfones and sulfoximines.

Tetraphosphine cis,cis,cis-1,2,3,4-tetrakis[(diphenylphosphino)methyl]cyclopentane (Tedicyp) is an efficient ligand for the Heck reaction of sulfur-containing alkenes with aryl bromides. The rates and yields of the reactions strongly depend on the oxidation state of the sulfur atom.
