N‐tosylhydrazones: The direct formation of ketenimines from carbenes and isocyanides is limited to the reaction of Fischer carbene complexes or some specially stabilized carbenes with isocyanides. A Pd‐catalyzed amidation of N‐tosylhydrazones with isocyanides via a ketenimine intermediate in the presence of water is described. The method offers a general way to synthesize amides from carbonyl compounds through one‐carbon
N-甲苯磺酰hydr的氨基羰基化作用:由卡宾和异氰酸酯直接形成酮亚胺的过程仅限于Fischer卡宾配合物或某些特别稳定的卡宾与异氰化物的反应。描述了在水的存在下,通过一个烯酮亚胺中间体,钯催化的N-甲苯磺酰with与异氰酸酯的酰胺化反应。该方法提供了通过单碳延伸从羰基化合物合成酰胺的通用方法(参见方案)。
