We describe herein a simple, fast and inexpensive protocol for the oxidative coupling of thiols employing a stoichiometric amount of DMSO and iodine as the catalyst. Various aromatic disulfides were obtained in good to excellent yields in short reaction times at room temperature, while aliphatic disulfides were achieved in good yields when the reactions were conducted under microwave irradiation.

使用I ₂ / DMSO催化系统，无溶剂和无金属的硫醇选择性氧化为二硫化物

我们在本文中描述了一种简单，快速和廉价的方案，该方案使用化学计量的DMSO和碘作为催化剂进行硫醇的氧化偶联。在室温下，在短的反应时间内，可以以高至极好的收率获得各种芳族二硫化物，而在微波辐射下进行反应时，可以高收率获得脂族二硫化物。
