Thiols are important building blocks for the synthesis of a variety of pharmaceutically important sulfur-containing compounds. Due to the versatile functionalities in organic synthesis, Herein, we report the development of thiols synthesis via rhodium-catalyzed hydrogenation of RS-SR. Green and clean hydrogen is used as the reductant. This transformation exhibits excellent functional group tolerance, a wide range of aryl or alkyl disulfides were reduced to the corresponding thiols in good to excellent yields with a loading of rhodium catalysts down to 0.05 mol%. This reaction also can be carried out at a large gram scale. And the catalysts can be recycled three times without diminishing the catalytic activity. All of these show that this method for hydrogenation of disulfide has great potential for industrial production.
