A novel potassium tert‐butoxide‐mediated amine acyl exchange of N,N‐disubstituted formamides with aromatic carbonyl derivatives in a sequential CN bond cleavage/formation process leading to aromatic amides is described. This methodology tolerates a wide range of aromatic carbonyl compounds, including aromatic aldehydes, acyl chlorides, unactivated esters, and acid anhydrides. The usage of inexpensive
描述了一种新的叔丁醇钾介导的N,N-二取代甲酰胺与芳族羰基衍生物的连续CN键裂解/形成过程,导致芳族酰胺的胺酰基交换。这种方法可以耐受多种芳香族羰基化合物,包括芳香族醛,酰氯,未活化的酯和酸酐。使用廉价且容易获得的试剂,广泛的底物范围以及简单,温和的(50°C)和无过渡金属的条件使该方案非常实用。此外,根据实验观察结果,提出了合理的反应机理。
