Abstract: Disclosed are methods for preparing disulfide compounds through oxidative coupling of thiol compounds. Thiols are oxidized to the corresponding disulfide compound in high yield in presence of a base and a metal salt. The method uses low catalyst loadings and provides organic disulfide compounds with little to no byproducts.

Abstract translation: 公开了通过硫醇化合物的氧化偶联制备二硫化物的方法。 在碱和金属盐的存在下，硫醇以高产率氧化成相应的二硫化物。 该方法使用低催化剂负载量，并提供几乎没有副产物的有机二硫化物。
