Abstract
Acid hydrolysis of triphenylphosphite (1) are effectively catalyzed by anionic micelles of sodium lauryl sulfate (NaLS), alkylhydrogensulfate (2), tetradecanesulfonic acid (3a) and p.decyloxybenzenesulfonic acid (3b). Cationic micelles of cetyltrimethylammonium chloride (CTACI) inhibit the reaction. Rate effects were analyzed quantitatively in terms of distribution of reactants between water and the micelles; and the effect of added HCl or salt can be explained quantitatively in these terms.
