here a novel and straightforward synthesis method for the preparation of α-aminophosphonates in relatively good yield. The method involves the one-pot three-component condensation of alcohols, amines, and diethylphosphite in the presence of CuO@Fe3O4 nanoparticles as a recyclable catalyst. CuO@Fe3O4 nanoparticles were prepared and their structures were confirmed by the FT-IR, TGA, VSM, TEM and X-ray
我们在这里报告了一种新颖而直接的合成方法,用于以相对较高的产率制备α-氨基膦酸酯。该方法涉及在CuO @ Fe 3 O 4纳米颗粒作为可循环利用催化剂的情况下,将醇,胺和亚磷酸二乙酯进行一锅三组分缩合。制备了CuO @ Fe 3 O 4纳米粒子,并通过FT-IR,TGA,VSM,TEM和X射线衍射图谱分析证实了其结构。
