Kinetics of nucleophilic substitution reactions in ordered media

The kinetics of the base hydrolysis of nucleophilic substitution involving O-alkyl-O-(p-nitrophenyl)chloromethylphosphonates in direct micelles of cet ylpyridinium bromide and cetyltrimethylammonium bromide and in the ternary reversed micellar system (sodium dodecyl sulfate-hexanol-water), as well as the kinetics of the reactions of these compounds with hexylamine in revers ed micelles of polyethylene glycol-600 monolaurate in toluene were studied, It was shown that the direct micelles have a differentiating action on the reactivity of the substrate, whereas the reaction rate in reverse micelles only slightly depends on the hydrophoby of the substrate.
