Abstract: | Processes of cleavage of 4-nitrophenyl esters of diethylphosphoric, diethylphosphonic, and 4-toluenesulfonic acids were investigated occurring in micelles of surfactants containing supernucleophilic oximate fragment and on their analogs not forming micelles in water. At transferring the reaction from water into the micelles of functional surfactants the reaction accelerates 102?C103 times. This acceleration is caused by the concentration of the substrate, for the nucleophilicity of the oximate fragment changes insignificantly. The reactivity of the functional surfactants is described by the Br?nsted dependence with a break, its character is analogous to the dependence of the oximes non-forming micelles. |
