Abstract α-(4-antipyryl)amino-(substituted)phenylmethylphosphonic acid diesters (2) were synthesized by the addition of phosphite diesters to corresponding imine (1). A five-member cyclic transition state was proposed, and the influence of substituents on the reactivity of substrate was discussed. The net atomic charges of some imine 1 was calculated to support the mechanism. In the presence of NaI
摘要 通过将亚磷酸二酯加成到相应的亚胺 (1) 上,合成了 α-(4-antipyryl) 氨基-(取代) 苯基甲基膦酸二酯 (2)。提出了五元环状过渡态,并讨论了取代基对底物反应性的影响。计算了一些亚胺 1 的净原子电荷以支持该机制。在 NaI 或 KI 存在下,2a 和 2c 的甲酯的裂解完全通过 2 与三甲基氯硅烷的三甲基甲硅烷基化实现。化合物的结构经1H NMR谱确证。
