  Multifunctional transformation of amide C–N bond cleavage is reported. The protocol applies to benzamide, thioamide, alcohols, and mercaptan under similar reaction conditions catalyzed by NaOTs. It is noteworthy that NaOTs can not only be recycled and reused for up to three cycles without significant loss in catalytic activity, but also catalyze gram-grade reactions. This study provides a novel solution

  报道了酰胺C-N键断裂的多功能转化。该协议适用于在 NaOT 催化的类似反应条件下的苯甲酰胺、硫代酰胺、醇和硫醇。值得注意的是，NaOTs 不仅可以回收和重复使用多达三个循环而不会显着降低催化活性，而且还可以催化克级反应。本研究为多种酰胺的转化提供了一种条件温和、程序简单的新型解决方案。

  unprecedented IrIII[df(CF3)ppy]2(dtbbpy)PF6-catalyzed simple photochemical process for direct addition of amines and alcohols to the relatively less reactive nitrile triple bond is described herein. Various amides and esters are synthesized as the reaction products, with nitriles being the acid equivalents. A mini-library of different types of amides and esters is made using this mild and efficient process, which
