A ligand-free palladium-catalyzed hydroxycarbonylation of aryl halides provides the corresponding aromatic carboxylic acids in high yields with high selectivity at room temperature and atmospheric pressure. The new method is operationally simple and scalable. In addition, aromatic esters were easily synthesized through hydroxycarbonylation followed by a one-pot alkylation with alkyl halides.
