Established carboxylic acids to nitriles conversion methods suffer from expensive catalysts, tedious steps, high temperatures (>200 °C), high pressure, or a narrow substrate range. Herein, we demonstrate a concise and efficient access to diverse nitrile compounds from ubiquitous carboxylic acids with electron-deficient N-cyano-N-aryl–arylsulfonamide (NCAS) in moderate to excellent yields. This strategy
已建立的将羧酸转化为腈类的方法存在昂贵的催化剂、繁琐的步骤、高温 (>200 °C)、高压或窄底物范围等问题。在此,我们展示了一种从普遍存在的羧酸和缺电子的N-氰基-N-芳基-芳基磺酰胺 (NCAS) 中以中等到优异的收率从普遍存在的羧酸中简明有效地获取多种腈化合物的途径。该策略由廉价的铁催化剂促进,并且通常与伯、仲、叔和芳基羧酸以及各种官能团相容。
