The self-organization of the poly(ethylene glycol)(10)monododecyl ether (C12EO10)/poly(ethyleneimine) (PEI)/La(III)/water multicomponent system has been examined in the micellar and liquid-crystalline ranges. A step-by-step investigation of the catalytic effect toward the cleavage of phosphorus acid esters was performed for the following series:  single C12EO10micelles → ternary C12EO10/PEI/water micellar system → quaternary C12EO10/PEI/La(III)/water micellar system → liquid-crystalline mesophase. The quaternary system was found to be an effective nanosized catalyst, demonstrating the complex mechanism of the catalytic action under mild conditions (25 °C, pH 8.0) and the substrate specificity toward the more hydrophobic phosphonate. A marked (ca. 1000-fold) acceleration of the reaction studied as compared to the basic hydrolysis of the substrates was achieved.

A correlation between salt-induced structural transitions of dodecylpyridinium bromide micelles and their catalytic effect on the basic hydrolysis of O-ethyl O-p-nitrophenyl chloromethylphosphonate has been found.

A kinetic study of the basic hydrolysis of the substrate in a sodium bis(2-ethylhexyl)sulfosuccinate-decane-water reverse micellar system has shown a change in the reactivity of p-nitrophenyl ethyl chloromethyl phosphonate above the percolation threshold. The applicability of the pseudophase model of micellar catalysis, below and above the percolation threshold, is shown.

The catalytic effect in the title system was found to depend on the nature of surfactants and substrates and on the surfactant-to-poly(ethylenimine) ratio.

The reactivity of the substrates in the title system is mainly determined by the electronic effect of substituents and slightly influenced by their hydrophobicity.

The reactivity of ethyl aryl chloromethylphosphonates in the basic hydrolysis reactions in direct micelles of cetyltrimethylammonium bromide depends on both electronic and hydrophobic properties of the substituent in the aryl group, while in the sodium dodecyl sulfate–hexanol–water micellar system it depends only on the electronic nature.

Self-association of long-chain amines and formation of mixed micelles, including cetylpyridinium bromide, influence the rate and the direction of the O,O-(bis-p-nitrophenyl)methylphosphonate hydrolysis; characteristic parameters of the micellar aggregates have been obtained by kinetic methods and 1H NMR spectroscopy.

The kinetics of the basic hydrolysis of ethyl p-nitrophenyl ethylphosphonate in the sodium dodecyl sulfate–hexanol –water reverse micellar system has shown that at high pH and low water content the reaction occurs in the surface layer and is adequately described by a pseudophase model.

The results of a kinetic study have shown that the reactivity of monomeric forms of amphiphilic tetra- ([H4L]4-) and octa- ([L]8-) anions of calix[4]resorcinolarenes (H8L) towards p-nitrophenyl esters of tetracoordinated phosphorus acids in aqueous dimethylformamide (50 vol.% of DMF) is determined by the nucleophilic centres of the anions, whereas an increase in the concentration of H8L inhibits the process, which is due to the formation of aggregates.

The influence of KCl, KBr and sodium salicylate (NaSal) on the micellar effect of cetylpyridinium bromide in the alkaline hydrolysis of p-nitrophenyl ethyl chloromethylphosphonate has been studied and the effects of electrolytes on the rate constant and surface potential compared; based on the data obtained, it can be concluded that the reaction inhibition is determined both by a change in the structure and properties of the micellar aggregates and by a decrease in the concentration of the nucleophile in the micelles due to a decrease in the surface potential.
