photoexcitation of aryl(hetero)diazonium salts and sulfonamides enabled this strategy under visible-light irradiation through an EDA complex used to carry out a one-step synthesis without a catalyst. This approach tolerated various functional groups of primary sulfonamides and (hetero)aryl diazonium salts, frequently found in modern medications and pharmacological intermediates. This method also enabled
在制药领域,功能化芳基磺酰胺是基本组成部分。芳基(杂)重氮盐和磺酰胺的光激发通过 EDA 复合物在可见光照射下实现了这一策略,该复合物用于在没有催化剂的情况下进行一步合成。这种方法可以耐受现代药物和药理中间体中常见的伯磺酰胺和(杂)芳基重氮盐的各种官能团。该方法还能够实现仲磺酰胺的直接芳基化。机理研究表明,形成的电子给体受体EDA复合物和磺酰胺自由基通过自由基偶联与芳基自由基中间体快速相互作用,生成所需产物。
