TBADT/nickel co-catalyzed three-component radical acylarylation of alkenes with aldehydes and aryl iodides

Résumé fourni par la source

Here we report a photo/nickel co-catalyzed three-component acylarylation of alkenes using aldehydes and aryl iodides. Tetrabutylammonium decatungstate (TBADT) serves as a hydrogen-atom-transfer (HAT) photocatalyst and works synergistically with nickel catalyst for this radical acylarylation. This method provides a versatile and modular strategy for synthesizing β -aryl ketones directly from readily available aldehydes under mild conditions.
