, p. 1030 - 1033 (1990)
The probable telomerization mechanism was studied by IR spectroscopy, according to which the reaction of 1,3-dienes with sulfinic acids proceeds through a stage of formation of S-sulfinate complexes of palladium, which bring about the formation of molecules of unsaturated sulfones.

Although benzyne has been well-known to serve as a synthon that can conveniently prepare various 1,2-difunctionalized benzenes, the sites other than its formal triple bond remain silent in typical benzyne transformations. An unprecedented aryne 1,2,3,5-tetrasubstitution was realized from 3-silylbenzyne and aryl allyl sulfoxide, the mechanistic pathway of which includes a regioselective aryne insertion into the SO bond, a [3,6]-sigmatropic rearrangement, and a thermal aromatic 1,3-silyl migration cascade.

A facile synthetic method for the preparation of allyl sulfoxides byS-allylation of sulfinate esters proceeds through sulfonium intermediates without [3,3]-sigmatropic rearrangement and further Pummerer-type reactions of the resulting allyl sulfoxides. On the basis of the plausible reaction mechanism involving sulfonium salt intermediates,S-alkynylation andS-arylation were also accomplished.

supporting information, p. 2086 - 2089 (2016/06/01)
A one-pot process for the synthesis of unsymmetrical sulfoxides using organometallic nucleophiles is described. Sulfur dioxide, delivered from the surrogate DABSO (DABCO-bis(sulfur dioxide)), acts as the initial electrophile and combines with the first organometallic reagent to generate a sulfinate intermediate. In situ conversion of the sulfinate to a sulfinate silyl ester, using TMS-Cl (trimethylsilyl chloride), generates a second electrophile, allowing addition of a second organometallic reagent. Organolithium or Grignard reagents can be employed, delivering sulfoxides in good to excellent yields.

, p. 7449 - 7454 (2007/10/03)
Palladium-catalyzed allylic alkylation of sulfenate anions, generated from β-sulfinylesters by retro-Michael reaction, can take place under biphasic conditions. This new reaction provides a simple, mild, and efficient route to allyl sulfoxides in good yields.
STRUCTURAL EFFECTS UPON COMPETITIVE DECOMPOSITION PATHWAYS OF THIOSULFOXIDE INTERMEDIATES
Baechler, Raymond D.,Filippo, Lynn James San,Schroll, Alayne
, p. 5247 - 5250 (2007/10/02)
Mixtures of sulfides and disulfides are obtained upon reaction of boron trisulfide with a series of allyl aryl sulfoxides, with the product distributions dependent upon the structures of the intermediate thiosulfoxides.
