Apparent second-order rate constants (k2(app)) for the reaction of 2-iodosylbenzoate with 4-nitrophenyl diphenyl phosphate (3), 4-nitrophenyl acetate (4), 1-methylethyl methyl-phosphonofluoridate (5), 1,2,2-trimethylpropyl methylphosphonofluoridate (6) and ethyl N,N-dimethylphosphoramidocyanidate (7) in solutions of cetyltrimethylammonium bromide (ctab) were determined over a range of ctab concentrations.The profiles of k2(app) against were analysed to obtain second-order rate constants for the reaction in the micellar phase, and stability constants for the binding of reactants to the micellized detergent.Reaction rates in the micellar and bulk aqueous phases for each substrate are indistinguishable.The rate enhancements provided by the micellized ctab result from concentrating the reactants in the micellar phase.Substrates (5)-(7) are much less strongly bound to the micellized detergent than (3), and the maximum rate enhancements for these substrates are correspondingly smaller.
