, p. 5169 - 5176 (2021/06/21)
The addition reaction of thiol to vinyl azide has been extensively studied. Variously substituted aryl thiols are all viable for this coupling process. The scope of the other partner is successfully expanded from α-aryl vinyl azide to α-alkyl vinyl azide.

Sulfoxonium ylides as safe carbene precursors are described for iridium-catalyzed carbene insertions and annulation, providing a facile and green approach to access a variety of quinoxaline derivatives in water. This water-mediated method also allows the preparation of β-keto thioethers under mild condition.

A new and facile KI/K 2 S 2 O 8 -mediated α-C-H sulfenylation of carbonyl compounds with (hetero)aryl thiols was developed for the formation of C-S bond at room temperature. This method provided a simple process for the sy
Catalyst-Free Difunctionalization of Activated Alkenes in Water: Efficient Synthesis of β-Keto Sulfides and Sulfones

, p. 14489 - 14493 (2016/10/03)
Difunctionalization of activated alkenes, a powerful strategy in chemical synthesis, has been accomplished for direct synthesis of a series of β-keto sulfides and β-keto sulfones. The transformation, mediated by O2, proceeds smoothly in water and without any catalyst. Prominent advantages of this method include mild reaction conditions, purification simplicity, and gram-scale synthesis, underlining the practical utility of this methodology.
Catalyst-Free Insertion of Sulfoxonium Ylides into Aryl Thiols. A Direct Preparation of β-Keto Thioethers
Dias, Rafael M. P.,Burtoloso, Antonio C. B.
, p. 3034 - 3037 (2016/07/06)
Insertion of sulfoxonium ylides into the S-H bond of aryl thiols without the need for a catalyst is demonstrated, furnishing β-keto thioethers in excellent yield in most cases. The method overcomes traditional syntheses that employ metal catalysts in combination with diazo compounds or toxic and hard-prepared haloketones. The experimental setup consists of mixing the reagents in acetonitrile at room temperature. Additional experimental as well as kinetic isotopic effect studies give some insight into the mechanism of this reaction.

Gold-catalyzed carbene transfer to alkynes: Access to 2,4-disubstituted furans
Kramer, Soren,Skrydstrup, Troels
supporting information; experimental part, p. 4681 - 4684 (2012/06/30)
Furans of gold: The first example of a gold-catalyzed intermolecular addition of carbon ylides to terminal alkynes is reported (see scheme; DCE=dichloroethane, Tf=trifluoromethanesulfonyl). Subsequent intramolecular trapping of the generated gold carbene completes a formal [3+2] cycloaddition, which represents a novel synthesis of 2,4-disubstituted furans. Copyright
