Reactivity of mixed micellar systems based on the functionalized imidazolium and tetraalkylammonium surfactanats in the reaction of cleavage of 4-nitrophenyl ethyl ethylphosphonate was studied. Replacing of an imidazolium fragment in the detergent structure with a tetraalkylammonium one reveals decreasing the substrate solubilization efficiency. In the case of dimeric surfactants, the nucleophilicity of the oximate fragment is considerably (ca. 2 times) decreased thus additionally decreasing the rate of cleavage of the organophosphorus substarte. Therefore the nature of the cationic center in the head group may affect the extent of the observed micellar effects of functionalized surfactants.
