Recent Advances in Deoxygenative Thioether Synthesis Using Oxygenated Sulfur Surrogates

Synthesis, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 9, 2025

Abstract Thioethers (sulfides) play a crucial role in therapeutics, diagnostics, and functional materials. Traditionally, their synthesis involved the use of thiols or derivatives, which are associated with unpleasant odors potential health risks. Recently, significant research has focused on employing oxygenated sulfur compounds, such as sulfinates, sulfonyl oxyacids, sulfoxides, thiol surrogates for thioether synthesis. This review highlights recent advancements deoxygenative synthesis, categorizing them by reaction types, including cross-coupling reactions, C–H functionalization, hydro/halo/oxy-thiolation unsaturated hydrocarbons. We also discuss representative mechanisms to provide comprehensive understanding these innovative approaches. 1 Introduction 2 Cross-Coupling Reactions 3 Functionalization 4 Hydro/Halo/Oxy-thiolation Unsaturated Hydrocarbons 5 Conclusion

Radical 1,3-Hydrosulfonylation of Vinyldiazo Compounds with Sulfinyl Sulfones

Organic Letters, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 4, 2025

Sulfinyl sulfones, as high-valence sulfurization reagents, are widely used to assemble sulfur sources on carbon skeletons, such one-, two-, and four-carbon synthons, access organosulfur compounds. However, their reaction with three-carbon synthons has remained a mystery until now. We report here radical 1,3-hydrosulfonylation of vinyldiazo compounds sulfinyl sulfones. This not only represents the first example sulfones but also opens up application in monofunctionalization.
