Zinc oxide nanoparticles (ZnO NPs, ca. 22 nm) were used as an effective catalyst in the solvent-free, three-component couplings of aldehydes, aromatic amines and dialkyl phosphites at room temperature to produce various α-amino phosphonates. Compared to known methods, satisfactory results were obtained with high yields through a simple experimental procedure. The catalyst was recycled and reused five times with minor decrease in its catalytic activity.
氧化锌纳米颗粒(ZnO NPs,约22纳米)被用作有效催化剂,在无溶剂的条件下,室温下对醛、芳香胺和双烷基磷酸酯进行三组分耦合反应,以生成各种α-氨基膦酸酯。与已知方法相比,通过简单的实验程序获得了满意的结果,产率高。该催化剂经过回收和重复使用五次后,其催化活性仅略有下降。
