Reactivity of α-nucleophilic groups in functional detergents was shown to be comparable with that of non-micelle-forming analogues. The routes for surfactant modification aimed at creation of supernucleophilic systems for cleavage of organophosphores were suggested. New functional detergent - 1-cetyl-3 (2-oximinoethyl) imidazolium chloride - is the most powerful among surfactants known, capable, under optimum condition, to achieve half-lives of 4-nitrophenyl diethyl phosphonate and of 4-nitrophenyl diethyl phosphate ≤2 and 14 s respectively.


Key word functional surfactants, organophosphorous compounds, nucleophility, micellar effects.
