A mild and practical method for synthesizing sulfonyl derivatives, which have a wide range of applications in pharmaceuticals, materials, and organic synthesis, was described through the oxidative functionalization of thiols with DMSO/HBr. The simple conditions, low cost and ready availability of DMSO/HBr, as well as the versatility of the transformations, make this strategy very powerful in synthesizing
通过二甲基亚砜/溴化氢对硫醇进行氧化官能化,描述了一种温和实用的合成磺酰衍生物的方法,该衍生物在药物、材料和有机合成中具有广泛的应用。DMSO/HBr 的简单条件、低成本和易得性,以及转化的多功能性,使得该策略在合成各种磺酰衍生物(包括磺酰胺、磺酰氟、磺酰叠氮化物和磺酸盐)方面非常有效。机理研究表明,DMSO 作为末端氧化剂,HBr 既作为亲核试剂又作为氧化还原介体来转移氧原子。
