Cu(II)/Photoredox-Catalyzed Aminoacylation of Vinyl Bromides

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

Published: March 24, 2025

A novel C–C coupling reaction of vinyl bromides with carboxamides has been developed through Cu(OAc)2/photocatalysis. This process features regioselective carboxamido carbon-vinylation under mild conditions. Mechanistic studies suggest that the formation an acyl-Cu(I) intermediate plays a crucial role regard to enabling this transformation.

Published: May 19, 2025

Comprehensive Summary Visible light‐induced transformation of CO 2 and CS into value‐added products has attracted worldwide attention because it mimics nature. In this context, although visible‐light‐induced direct synthesis dithiocarbamates carbamates employing SO as a C1 source been reported, all these reactions are limited to the preparation S ‐alkyl mono‐dithiocarbamates O mono‐carbamates. Herein, we report visible‐light photoredox‐catalyzed multicomponent reaction diazosulfonium triflates with amines or . Mechanistic studies indicate that diazomethyl radicals might be generated key intermediates, thus providing direction for application other radical acceptors.
