    • Abstract

       

      The esterification of thiodiglycol and long alkyl-chain carboxylic acids is reported. Reaction of thiodiglycol with carboxylic acid via 𝑝-TsOH/C-catalysed direct esterification afforded thiodiglycol dicarboxylic acid esters in good yields and chemoselectivity. The use of immobilized 𝑝-TsOH on activated carbon as catalyst is crucial for the transformation.
