The reaction of phosphorus trichloride in acetic acid or phosphonic (phosphorous) acid in acetic anhydride, with N-(triphenylmethyl)alkanimines gives 1-acetylaminoalkylphosphonic acids 1a-j, which after hydrolysis give 1-aminoalkylphosphonic acids 2a-j in good yields.
三氯化磷在乙酸中或在乙酸酐中的膦酸(亚磷酸)与 N-(三苯基甲基)链烷胺反应生成 1-乙酰氨基烷基膦酸 1a-j,水解后生成 1-氨基烷基膦酸 2a-j,收率良好。
