Abstract
An electrolytic method for the simultaneous preparation of a diaryliodonium salt and an alkoxide salt comprises adding to the anode compartment of an electrolytic cell, comprised of an anode, a first electrolytic solution comprising an aromatic compound, an iodoaromatic compound, a solvent and a first organic salt; adding to the cathode compartment of the cell, comprised of a cathode, a second electrolytic solution comprising a hydroxyalkyl compound and a second organic salt; and applying to the anode and the cathode an electric potential, to form diaryliodonium salt in the anode compartment and an alkoxide salt in the cathode compartment. Esters of an aromatic acid are prepared by carbonylating an admixture of the diaryliodonium salt and the alkoxide salt by the addition of carbon monoxide thereto.
