description This invention relates to a process for the production of an aryl thiol, which comprises hydrogenating an aryl sulfonyl chloride in a solvent in the presence of a palladium catalyst and a base whose conjugate acid has a pKa of about 2 or greater, wherein the base is selected from the group consisting of ionic bases soluble in water and tertiary amines soluble in the solvent, the tertiary amines not having a methyl group attached to the amine nitrogen.
