The reactions of p‐nitrophenyl acetate (PNPA) and p‐nitrophenyl benzoate (PNPB) with α‐nucleophileoximates, that is, butane 2,3‐dione monoximate, pralidoximate, and other oximates have been studied in the presence of different cationic surfactants. The first‐order rate constant increases with increasing surfactant concentration. The extent of acceleration is dependent on the head group structure of

71) fitting the 0.5−0.7 range commonly found for SNAr reactions, those for the various oximates studied do not define a meaningful linear plot. Interestingly, the observed variations in k1Ox reveal a tendency of the reactivity of oximates of pKa > 7.5−8 to level off rapidly, a situation reminiscent of that encountered in other nucleophilic reactions of these species at carbonyl and phosphonyl centres
