Abstract
A process for replacing an aromatic carbon-thallium bond with a carbon-oxygen bond. The process is particularly suitable for producing specific aromatic isomers by thallating an aromatic compound and replacing the thallium with a carboxylate group which can be further hydrolyzed if desired to form an aromatic hydroxyl compound.
