- Title

- Abstract
Abstract: Herein, a new catalytic system to synthesize benzofuranones is reported. A palladium‐catalyzed intramolecular alkoxycarbonylation is employed to generate 3‐substituted‐benzofuran‐2(3<italic>H</italic>)‐ones from alkenylphenols under mild reaction conditions, linked to an ex situ formation of CO from <italic>N</italic>‐formylsaccharin. The carefully chosen catalytic system enables an efficient reaction with a novel functional group tolerance, despite the high polymerization tendency of the starting material.
