Photoredox-Catalyzed Three-Component Sulfonaminoalkynylation of Alkenes via a Radial/Polar Crossover

The Journal of Organic Chemistry, Год журнала: 2025, Номер 90(4), С. 1656 - 1662

Опубликована: Янв. 21, 2025

We report a photoredox-catalyzed three-component sulfonaminoalkynylation of alkenes with N-aminopyridine salts and potassium alkynyltrifluoroborate salts. This aminoalkylation reaction underwent radial/polar crossover mechanism, which was distinguished from the previous reports. A variety β-alkynylated sulfonamides were obtained in moderate to excellent yields. The versatility this method further evidenced by its successful application modifying biological molecules advanced stages development.

Recyclable Ag/g‐C3N4 Catalyzed Visible‐light Promoted Heterogeneous Synthesis of Unsymmetric Diaryl Chalcogenides

Asian Journal of Organic Chemistry, Год журнала: 2024, Номер unknown

Опубликована: Окт. 27, 2024

Abstract With Ag/g‐C 3 N 4 semiconductor as the heterogeneous photocatalyst, visible light promoted synthesis of unsymmetric diaryl chalcogenides could be achieved under additive‐free and mild conditions. A series were generated in good to excellent yields with high functional group tolerance. The photocatalyst is easily recovered from reaction mixture reused at least 5 times, opening way for larger‐scale industrial applications this type photocatalytic bond‐forming reactions.
