摘要

摘要:对二羟基苯基膦酸盐的制备方法进行了评价。一方面，h -苯基膦酸盐氧化得到相应的苯基膦酸单酯;另一方面，苯基膦酸可通过微波辅助直接酯化制备苯基膦酸盐。以离子液体为催化剂，在毫瓦辐射下进行了与醇的反应。在三乙胺存在下，在微波条件下与烷基卤化物进行烷基化酯化反应，建立了第二酯功能。图形抽象

Microwave-assisted esterification of P-acids

The possibilities for the preparation of dialky phenylphosphonates were evaluated. On the one hand, the oxidation of phenyl-H-phosphinates gave the corresponding phenylphosphonic acid monoesters. On the other hand, phenylphosphonates may be prepared by MW-assisted direct esterification of phenylphosphonic acid. The reaction with alcohols was performed under MW irradiation in the presence of an ionic liquid as the catalyst. The second ester function was established by alkylating esterification carried out with alkyl halides in the presence of triethylamine under MW conditions.
