aminomethylated calix[4]resorcinolarenes (AMC) withp-nitrophenyl esters of phosphorus acids (EPA) in a water—DMF solution (30 vol.% DMF) was studied by spectrophotometry and31P NMR spectroscopy in the presence and absence of the nonionic surfactant Triton X-100. The AMC form aggregates of micellar and nonmicellar types and are the catalysts for EPA hydrolysis. The catalytic activity of the aggregates depends on
通过分光光度法和 31 P NMR 光谱研究了氨基甲基化杯[4]间苯二酚 (AMC) 与磷酸的对硝基苯酯 (EPA) 在水-DMF 溶液 (30 vol.% DMF) 中的反应动力学。非离子表面活性剂 Triton X-100。AMC 形成胶束和非胶束类型的聚集体,是 EPA 水解的催化剂。聚集体的催化活性取决于它们的结构、介质的 pH 值和溶剂的性质。
