Nucleophilic reactivity of a typical α-nucleophile - hypobromite ion generated by organocomplexes of tribromide ions with respect to 4-nitrophenyl diethyl phosphonate in water and micelles of cetyl- trimethylammonium bromide (CTABr) was studied. The BrO--CTABr system is one of the most effective for decomposition of organophosphorous compounds: the effect of reagent concentrating ensures quick decomposition of 4-nitrophenyl diethyl phosphonate in aqueous micellar medium with t1/2 ≤ 20 s (t1/2 600 s in water).


Key words reactivity, hypobromite ion, 4-nitrophenyl diethyl phosphonate, surfactants.
