Photoinduced Carboarylation of Alkenes by Using Bifunctional Reagents

Abstract

Intermolecular alkene difunctionalization is an effective method for rapidly increasing molecular complexity with two valuable groups. We report a strategy for the photocatalytic radical-mediated desulfonylative carboarylation of alkenes by using strategically designed arylsulfonyl acetates as both arylating and carbonylating reagents. By using an Ir complex as a photocatalyst, aryl and carbonyl groups were simultaneously incorporated into alkenes to afford synthetically useful derivatives under mild reaction conditions. This transformation is characterized by a broad substrate scope and good functional-group compatibility. ©2023.Thieme. All rights reserved.Synlett 2023, 34, A–E
