## Abstract Pseudo‐first‐order rate constants have been determined for the nucleophilic substitution reactions of __p__‐nitrophenyl acetate with __p__‐chlorophenoxide (4‐ClC~6~H~4~O^−^) and __N__‐phenylbenzohydroxamate (C~6~H~5~CON(C~6~H~5~)O^−^) ions in phosphate buffer (pH 7.7) at 27°C. The effec
Reactions of p-nitrophenyl diphenyl phosphinate (p-NPDP) with OH- and F- are inhibited by micelles of dodecyl polyoxyethylene ethers C12E10 and C12E23. Rate constants decrease sharply in very dilute surfactant and become approximately constant as p-NPDP becomes fully micellar bound, with inhibition
