| Abstract: | The nucleophilic hydrolytic reactions of p-nitrophenyl diphenyl phosphate
(PNPDPP), p-nitrophenyl diethyl
phosphate (Paraoxon) and p-nitrophenyl
diethyl phosphorothioate (Parathion) with N-hydroxyamides have been
investigated at 27 °C. With
cationic micelles, rate enhancement has been observed on the nucleophilic
attack at P center. All the rate surfactant profiles show typical micelle
assisted bimolecular reactions. The interfacial ion exchange, control of the
interfacial nucleophile concentration and the reactivity at the micellar
interface has been explained. |
