  在砷酸催化剂存在下通过直接酯化二元膦酸合成烷基和芳基膦酸单酯

  摘要：

  二酯的部分水解、一氯单酯的水解或膦酸酐的醇解通常用于制备烷基-和芳基膦酸的单酯。已经报道了将二元膦酸酯化生成单酯的有限案例，这些方法都没有制备羧酸酯的类似方法那么简单，其中羧酸在存在下用醇酯化一种酸催化剂。描述了在催化量的苯胂酸存在下通过与醇直接酯化制备烷基-和芳基膦酸单酯的方法。在反应过程中形成的水​​被共沸除去。例如，甲基膦酸以良好的收率酯化得到其异丙基、丁基、环己基、冰片基和十八烷基单酯。类似地制备了苯基膦酸的乙基、丁基、己基和2-（乙硫基）乙基单酯，以及乙基膦酸2-异丙氧基乙基氢酯和苄基膦酸2-甲氧基乙基氢酯。
