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。

Complexation of N-alkyl(aryl)carbamoylmethylphosphine oxides (CMPO) and their N, N-dialkyl analogs in neutral media was studied. N-Alkyl derivatives react with praseodymium and europium nitrates both in solution and in the individual state to give 1: 2 and 1: 3 complexes, depending on the ratio of the starting reagents; for N-aryl amides, 1: 3 complexes were obtained only. With the uranyl cation, both

The basicity in nitromethane of carbamoylmethylphosphoryl compounds (CMP), RR' P(O)CHR''' C(O)NR2", containing different substituents at the phosphorus or nitrogen atoms and in the methylene bridge and binary reactants (CMP)2X, where X = (CH2)5 or p-CH2C6H4CH2, was investigated. The values of pK(a) are linearly correlated with SIGMA-sigma-P, the constant of the substituents at the phosphorus atom. Conformational analysis of CMP and tetraphenylmethylenediphosphine dioxides substituted in the methylene bridge showed that bulky substituents reduce the population of complexing conformations.
