Palladium‐Catalyzed Intermolecular Arylcarbonylation of Unactivated Alkenes: Incorporation of Bulky Aryl Groups at Room Temperature

Abstract

AbstractA palladium‐catalyzed intermolecular arylcarbonylation of unactivated alkenes has been developed. Unsymmetrical diaryliodonium salts (DAISs) were used as arylation reagents, the bulky aryl group (ArL) of which was exclusively incorporated into the arylcarbonylated products, which contained the ArL group and a carboxylic ester group at the α‐ and β‐carbon position, respectively, of the original terminal C−C double bond. The reaction features excellent chemo‐ and regioselectivity, high functional‐group tolerance, and very mild reaction conditions.
