摘要基于1-烷基-4-氮杂-1-氮杂双环[2.2.2]辛烷溴化物(Alk = C n H 2 n +1,n = 16,18)与硝酸镧的络合物的超分子体系的催化活性4-硝基苯基-O-烷基氯甲基膦酸酯的水解分解反应(Alk = C n H 2 n +1,n= 4、6)。发现由于各种尺寸和类型(小胶束和较大的超分子结构)的纳米级聚集体的形成而促进了反应,其有效地结合了试剂。膦酸酯与聚集体的结合常数大于三个或四个数量级。与配体相比,金属络合物体系的催化活性在溶液中的两亲物浓度较低时表现出来。

concentration, particle sizes and solubilization properties toward Orange OT were determined. Self‐assemblies organized by poly(11‐acryloyloxyundecyltrimethyl ammonium) bromide successfully catalyze the hydrolysis of 4‐nitrophenyl butylchloromethylphosphonate up to two orders of magnitude compared to aqueous alkaline hydrolysis. The development of these catalysts is promising for industrial applications

The effect ofn-decylammonium chloride/n-decylamine mixed micelles on the rate of hydrolysis of aryl esters of acids of four-coordinate phosphorus was studied spectrophotometrically. The shape of the concentration curves is characteristic of the micellar catalysis reactions. The binding constants of the substrate, critical micelle concentrations, and the rate constants in the micellar phase were determined

The catalytic effect of the sodium dodecyl sulfate-hexanol-water ternary reverse micellarsystem in the alkaline hydrolysis ofO-alkylO′-aryl chloromethylphosphonates as a function of the substrate structure was studied. The micellareffect is mainly determined by a change in the electronic properties of the substituents, while the hydrophobicity plays a secondary role. The kinetic data were examined

polyethyleneimines, mono- (MQD) and diquaternized (DQD) hexadecyl derivatives of 1,4-diazabicyclo[2.2.2]octane, and mixed polymercolloid systems based thereon catalyze the hydrolysis of p-nitrophenyl alkyl chloromethylphosphonates. The catalysis efficiency depends on the structures of substrate, 1,4-diazabicyclo-[2.2.2]octane derivatives, and polyethyleneimine, pH of the medium, and the temperature. In the case

used to study the catalytic effects of the systems composed of N-monoand N, N-dialkylated 1, 4-diazabicyclo[2.2.2]octanes and lanthanum nitrate on the hydrolysis rate of O-alkyl O-4-nitrophenyl chloromethylphosphonates (Alk = Et, Bun, and n-hexyl). The mechanism of action and efficiency of the catalytic system depend on the structure of the heterocycle, its propensity to aggregation and complexation
