reactions between amines and DMF to synthesize formamides. More than 20 amines, including primary, secondary, aromatic, and heterocyclic amines, diamines, and amino acids, are converted to the corresponding formamides with good‐to‐excellent conversions and selectivities under mild conditions. This strategy employs CO2 as a mediator to activate the amine under metal‐free conditions. The experimental
在本文中,我们报道了胺和DMF之间的CO 2介导的复分解反应以合成甲酰胺。在温和的条件下,包括伯,仲,芳族和杂环胺,二胺和氨基酸在内的20多种胺被转化为相应的甲酰胺,具有良好的转化率和选择性。该策略使用CO 2作为介质在无金属条件下活化胺。实验数据,原位NMR和衰减的全反射红外光谱测量结果表明,N-氨基甲酸是通过CO 2之间的弱酸碱相互作用而形成的中间体。和胺。易位氨基甲酸酯的形成驱动复分解反应,并提出了反应机理。
