A concise and practical silver-catalyzed nitrogen-atom-transfer protocol was developed to access versatile nitriles from ubiquitous carboxylic acids with N-cyano-N-phenyl-p-toluenesulfonamide. This protocol complements the established carboxylic acids-to-nitriles conversion methods, which suffer from laborious steps, high temperatures (≥200 °C), or limited substrate scopes. This approach operates broadly across diverse aryl, alkenyl, and primary-, secondary-, or tertiary-alkyl carboxylic acids.

银催化羧酸和氰胺合成腈

开发了一种简洁实用的银催化氮原子转移方案，以使用N -氰基 - N -苯基 - 对甲苯磺酰胺从无处不在的羧酸中获得多功能腈。该协议补充了已建立的羧酸到腈类转化方法，这些方法存在费力的步骤、高温（≥200 °C）或底物范围有限的问题。这种方法广泛适用于各种芳基、烯基和伯、仲或叔烷基羧酸。
