Carboxy-alkyl phenylphosphonic monoesters are obtained very easily by selective hydrolysis (in alcaline medium) of the corresponding carbamido- or cyano-alkyl phenylphosphonic monoesters and sometimes of the corresponding carbethoxy-alkyl phenylphosphonic monoesters and sometimes of the corresponding carbethoxy-alkyl phenylphosphonic monoesters and sometimes of the corresponding carbethoxy-alkyl phenylphosphonic
通过选择水解(在碱性介质中)相应的氨基甲酸酯基或氰基烷基苯基膦酸酯单酯,有时相应的羰基氧基烷基苯基膦酸酯单酯,有时有时相应的羰基氧基烷基苯基膦酸酯单酯,有时很容易地获得羧基烷基苯基膦酸酯单酯。相应的乙氧基烷基烷基苯基膦酸酯单酯。当-CONH 2,-CN或-COOR基团固定在带有苯基膦酸单酯基团的C旁边的C上时,无法执行此通用步骤。在这种情况下,单酯基团也可以在碱性介质中非常快地培养。
