The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(π-cinnamyl)Cl]2 enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this
描述了芳基磷酸酯的第一常规钯催化的胺化。MorDalPhos与[Pd(π-肉桂基)Cl] 2的结合可实现富电子,电子中性和贫电子的芳基磷酸酯与一系列芳族,脂族和杂环胺的胺化反应。在此反应条件下,常见的官能团(如醚,酮,酯和腈)显示出极好的相容性。无溶剂胺化反应在两种固体偶联剂中也都成功。通过这种催化系统可以实现克级交叉偶联。
