Alkylations of the stable diethyl N-(diphenylmethylene) aminomethylphosphonate (1) under solid-liquid phase-transfer catalysis (PTC) with or without solvent to give N-(diphenylmethylene) aminomethylphosphonic esters 2 are described. Acidic hydrolysis of 2 afforded diethyl (1-aminoalkyl)phosphonates 3 in good yields.
在固液相转移催化(PTC)条件下,稳定的二乙基N-(二苯基亚甲基)氨基甲基膦酸酯(1)的无溶剂或有溶剂烷基化反应得到了N-(二苯基亚甲基)氨基甲基磷酸酯2。酯2的酸性水解以良好的产率提供了二乙基(1-氨基烷基)膦酸酯3。
