A general, economical, and environmentally friendly method of amide synthesis from phenyl esters and arylamines was developed. This new method has significant advantages compared to previously reported palladium-catalyzed approaches. The reaction is performed transition metal- and solvent-free, using a cheap and environmentally benign base, NaH. This approach enabled us to obtain target amides in
开发了一种由苯酯和芳基胺合成酰胺的通用、经济和环保的方法。与先前报道的钯催化方法相比,这种新方法具有显着优势。该反应在无过渡金属和无溶剂的情况下使用廉价且对环境无害的碱 NaH 进行。这种方法使我们能够以高产率和高原子经济性获得目标酰胺。
