carbamoylmethylphosphine oxides (CMPO) in up to 96% isolated yield is developed via direct amidation of diphenylphosphoryl acetic acid in an ionic liquid as a recyclable reaction medium in the presence of triphenylphosphite. The influence of the nature of the amine and anion and cation structure in the ionic liquid on the reaction rate and yields of the products are also investigated. 1-Butyl-3-methylimidazolium
在亚磷酸三苯酯存在下,通过在离子液体中直接酰胺化二苯基磷酰基乙酸作为可循环的反应介质,可以方便地获得高达96%分离产率的氨基甲酰基甲基氧化膦(CMPO)。还研究了离子液体中胺,阴离子和阳离子结构的性质对反应速率和产物收率的影响。事实证明1-溴-3-甲基咪唑鎓溴化[bmim] Br和三己基十四烷基氯化phosph [P(C 6 H 13)3(C 14 H 29)] Cl是进行该反应的最佳介质。

A one-pot syntheticroute to phosphorylacetic acid N-aryl(alkylaryl)amides, including those containing two phosphorylmethylcarbamoyl moieties attached to the arene framework, has been developed. The method is based on reactions of amines with the corresponding acidchlorides generated in situ with the use of phosphorus trichloride as a mild chlorinating agent. The compositions and structures of the
