Abstract 2-Aminoethylphosphonic acid (AEPA) and its N-substituted compounds were prepared by one step reaction using 2-chloroethylphosphonic acid with ammonia and amines (H2NMe, HNMeMe, HNEtEt, H2NPr-n, H2NCH2ph, H2NCH2CH2NH2 and H2N(C=NH)NH2 in a dilute alkaline solution below 20 °C with simple work-up and easy purification. The reaction was accelerated by catalytic amount of potassium iodide. The
摘要 采用 2-氯乙基膦酸与氨和胺(H2NMe、HNMeMe、HNEtEt、H2NPr-n、H2NCH2ph、H2NCH2CH2NH2 和 H2N(C=NH))通过一步反应制备了 2-氨基乙基膦酸 (AEPA) 及其 N-取代化合物。 NH2在20℃以下的稀碱溶液中,后处理简单,易于纯化。催化量的碘化钾加速反应。反应产物的收率为35.6%~48.6%(不存在KI),78.2%~88.0%对于 KI 的存在。
