An electrochemically induced cross-dehydrogenative coupling of β-diketones and β-ketoesters with carboxylic acids provides intermolecular C-O coupling products in high yields using DMSO as a solvent in an undivided cell equipped with carbon and platinum electrodes at high current density. Electric current acts as a stoichiometric oxidant.
