Abstract Various diacyl disulfides are prepared easily in high yields from the corresponding acid chlorides under mild and non-aqueous conditions using a polymer supported reagent obtained from elemental sulfur and Amberlyst (OH). The polymericreagent is regenerable.
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.
