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

Cationic micelles of cetyltrimethylammonium bromide, CTABr, speed attack of hydroxide ion upon coumarin by a factor of c.a-2, due to a concentration effect. The first-order rate constants, at a given hydroxide ions concentration go through maxima with increasing k , obs surfactant concentration. The
Cationic micelles of alkyltrimethylammonium chloride and bromide (alkyl = n -C12H25, n-C14H29, and n-C16H33) catalyze and anionic micelles of sodium dodecyl sulfate inhibit the reaction of hydroxide ion with 2-phenoxyquinoxaline (1). Inert anions such as chloride, nitrate, mesylate, and n-butanosulf
