dc.description.abstract | The reactions between hydroxide or fluoride ion and p-nitrophenyl diphenyl phosphate, catalyzed by micelles of cetyltrimethylammonium bromide, are inhibited by phenyl, diphenyl, and p-t-butylphenyl phosphate. With decreasing pH the reaction with hydroxide ion becomes unimportant, and micellar-catalyzed reactions between the substrate and inorganic phosphate ions and phenyl and p-t-butylphenyl phosphate dianions can be observed. Diphenyl phosphate monoanion is unreactive. For the micellar catalyzed reaction the reactivity sequence is t-BuC6H4OPO3 2 > C6H5OPO3 2 > HOP4 2- and depends upon the nonbonding interactions between the cationic micelle and the nucleophilic anion, rather than their inherent nucleophilicities. The second-order rate constants for the micellar-catalyzed reaction with hydroxide ion agree well with those calculated at low pH in borate buffer. © 1969, American Chemical Society.
