摘要：
A method for the production of a sulfide group-containing thiol compound which comprises causing alkylene sulfide to react with a thiol compound in the presence of at least one basic catalyst selected from the group consisting of basic ion-exchange resins, quaternary ammonium compounds and alkyl pyridinium compounds, thereby inducing the ring-opening addition of the alkylene sulfide to the thiol compound. Further, a method for the production of a sulfide group-containing mercaptocarboxylic ester which comprises causing an alkylene sulfide to react with a mercaptocarboxylic ester.
