This protocol describes an iodine/manganese catalytic system for dehydrogenative oxidative coupling reaction of indoles with thiols in anisole. Particularly, the dual roles of anisole have been first demonstrated as a solvent and as a promoter via the formation of an oxonium ion intermediate to accelerate the generation of products. A series of sulfenylindoles are readily constructed under aerobic

吲哚与
硫醇的脱氢氧化偶联反应。特别是,
苯甲醚的双重作用已首先通过形成氧离子中间体以加速产物的产生而证明其作为溶剂和
促进剂。在需氧温和的反应条件下很容易构建一系列的亚磺酰基
吲哚。此外,制备抗癌和抗艾滋病药物的成就证明了这种方法的实用性。机制研究揭示了可能的替代途径,并且单电子转移过程也参与了这一转变。
