(Figure presented) Allylic sulfoxides, via [2,3]-sigmatropic rearrangement and oxidative addition of the resulting allylic sulfonate esters to Pd(0), are found to be excellent precursors of sulfenate anions. This hitherto unknown reactivity is applied in a new Pd(0)-catalyzed domino sequence involving sulfonate anion generation followed by arylation to afford aryl sulfoxides.

A novel and efficient method for selective synthesis of diaryl sulfoxides and m-arylthio sulfones has been achieved from readily available arylsulfinic acids and arenes via an unusual sulfinyl cation, providing a range of structurally diverse products in good to excellent yields under mild conditions. Notably, mechanistic investigations suggested m-arylthio sulfones were generated from diaryl sulfoxides and sulfinyl cation by a sequence of redox reaction and electrophilic aromatic substitution process.

An efficient, direct sulfinylation of organoborons catalyzed by palladium is disclosed. Treatment of organoborons and sulfinate esters in the presence of a palladium precatalyst provided a broad range of sulfoxides. Various organosulfur compounds having oxidizable functional groups were successfully prepared through the sulfoxide synthesis.

Abstract: A direct selective approach to the oxidation of sulfides to sulfoxides andsulfones with H2O2 in moderate togood yields is developed. The reaction proceeds in the presence of 2 mol % ofVO(acac)2 at room temperature. All sulfoxides andsulfones were detected by gas chromatography, and the molecular structures of2-methylbenzyl 4-methylphenyl sulfone, 4-methylbenzyl 4-methylphenyl sulfone,2-bromobenzyl 4-methylphenyl sulfone, and 4-tert-butylbenzyl benzyl sulfone were determined by singlecrystal X-ray crystallography.

A new transition-metal-free route for the direct sulfinylation of electron-rich aromatics with sodium arylsulfinates in the presence of TMSOTf is reported. Various electron-rich aromatics, including pyrroles, thiophenes, indoles, and electron-rich arenes, with sodium arylsulfinates are converted into the corresponding sulfoxides in moderate to excellent yields. This protocol possesses many advantages such as readily available and stable starting materials, broad substrate scopes, and transition-metal-free reaction conditions.

A facile and efficient visible-light-driven method has been developed to construct sulfoxides via oxidative coupling of aryldiazo sulfones with thiols using the O2 in air as the oxidant. This reaction could be performed at room temperature under catalyst- and additive-free conditions. The present methodology offers a mild and environmentally benign approach to obtain a library of sulfoxides in good yields with favorable functional group tolerance.
