  A Convenient Method for the Synthesis of Diacyl Disulfides

  摘要：

  A simple and general method for the synthesis of diacyl disulfides is reported. Sulfur is allowed to react with sodium hydroxide to give sodium disulfide at 65 degrees C under PTC, which can react with acyl halides to afford diacyl disulfides in good to excellent isolated yields. The effects of solvents and phase transfer catalysts are discussed.
