A simple and efficient protocol for silver(I)-catalyzed picolinamide directed C4–H amination of 1-naphthylamine derivatives with readily available azodicarboxylates has been developed, demonstrating a new approach to 1,4-naphthalenediamine derivatives in high yields. Note that this reaction system could proceed under external-oxidant- and additive-free conditions (only requires 5 mol % of AgOAc as
已经开发了一种简单有效的协议,用于银(I)催化的吡啶甲酰胺对1-萘胺衍生物的C4-H氨基化与易于获得的偶氮二羧酸酯的胺化反应,证明了一种高收率的1,4-萘二胺衍生物的新方法。注意,该反应体系可以在无外部氧化剂和无添加剂的条件下进行(仅需要5mol%的AgOAc作为丙酮中的催化剂)。
