Abstract We report a rapid, efficient, economic, environmentally benign, and easy to scale-up method for the synthesis of phosphonamide derivatives using ultrasound irradiation, under catalyst and solvent-free conditions starting from the corresponding amine and phenyl phosphonic dichloride. The reaction was achieved in excellent isolated yield in a short reaction time at room temperature. The structures
抽象的 我们报告了一种快速,有效,经济,环境友好,易于按比例放大的方法,该方法使用超声辐射,在无催化剂和无溶剂条件下,从相应的胺和苯基二氯化膦开始合成膦酰胺衍生物。在室温下,在短的反应时间内以优异的分离产率实现了该反应。通过元素分析以及IR和1 H,13 C,31 P NMR光谱数据和质谱确认合成的化合物的结构。
