reusable, and environmentally benign medium for the metal-free synthesis of α-aminophosphine oxide/phosphonate derivatives from one-pot, three-component hydrophosphorylation reactions of aldehydes, amines, and diphenylphosphine oxides/diethylphosphite. Here ChCl–urea (1 : 2) DES played a dual role, namely that of a solvent as well as an efficient catalyst. Using this protocol, diverse α-aminophosphorous derivatives
引入了含有氯化胆碱 (ChCl) 和尿素 (1:2) 的低共熔溶剂 (DES),作为一种高效、经济、可重复使用且环境友好的介质,用于无金属合成 α-氨基氧化膦/膦酸酯衍生物由醛、胺和二苯基氧化膦/亚磷酸二乙酯的一锅三组分加氢磷酸化反应产生。此处 ChCl-尿素 (1:2) DES 发挥双重作用,即溶剂和高效催化剂。使用该方案,在短时间内以优异的产率获得了多种α-氨基磷衍生物,并具有良好的官能团耐受性。
