aminolysis reaction between various aryl esters and inert tertiary amines by C–O and C–N bond activations has been developed for the selective synthesis of a broad scope of tertiary amides under neutral and mild conditions. The mechanism may undergo the two key steps of oxidative addition of acyl C–O bond in parent ester and C–N bond cleavage of tertiary amine via an iminium-type intermediate.
已开发出各种芳基酯与惰性叔胺之间通过C-O和C-N键激活进行的氨解反应,可在中性和温和条件下选择性合成各种叔酰胺。该机理可能经历了两个关键步骤:在母体酯中氧化加成酰基C–O键和通过亚胺基型中间体裂解叔胺的C–N键。
