Palladium-catalyzed carbonylation of iminoquinones and aryl iodides to access aryl p-amino benzoates

Abstract

A palladium-catalyzed carbonylation of iminoquinones and aryl iodides has been developed for the construction of aryl p-amino benzoates. Using benzene-1,3,5-triyl triformate (TFBen) as the CO source, the reaction proceeded well to give various aryl p-amino benzoates in good to excellent yields. Additionally, control experiments were conducted to gain more insights into the reaction mechanism.
