An unprecedented one‐step synthesis of N‐substituted hydrazones by coupling of alcohols with hydrazine is reported. This partial hydrogen‐borrowing reaction is catalyzed by a new manganese pincer complex under mild reaction conditions, thus liberating water and dihydrogen as the only byproducts. Mechanistic insight, based on the observation of intermediates, is provided.
据报道,通过醇与肼的偶合,空前的一步合成N-取代的azo酮。这种部分的氢借入反应是在温和的反应条件下由一种新型的锰钳配合物催化的,从而释放出水和二氢作为唯一的副产物。基于对中间体的观察,提供了机械学见解。
