Sulfone motifs play important roles in bioactive compounds and functional materials. The development of efficient methodologies for constructing sulfonyl-containing has thus attracted considerable attention. Here, we introduce a protocol the preparation alkyl aryl sulfones under mild conditions. This employs β-thioamide sulfone as novel motif donor. It forms sulfinates situ basic conditions, which then undergo cross-coupling with intermediates that were generated from ligand-free copper-catalyzed cyclopropenes (CPEs) ring opening.

Bis(dialkylaminethiocarbonyl)disulfides Act as Electron Acceptors for EDA Complexes for the Synthesis of Dithiocarbamate Derivatives under Visible Light

The Journal of Organic Chemistry, Год журнала: 2025, Номер unknown

This study proposes a green and efficient atom- step-economical method for converting hazardous CS2 to dithiocarbamate derivatives under visible light irradiation catalyst-free conditions. By the construction of novel C-S C-N bonds, series β-dicarbonyl compounds amines are incorporated into products. Under light, amine first form bis(dialkylaminethiocarbonyl)disulfides, which then react with K2CO3-activated electron donor-acceptor (EDA) complexes subsequently generate target confirms time that bis(dialkylaminethiocarbonyl)disulfides can act as acceptors an EDA complex compounds, coupled product light.
