摘要

Dephosphorylation of p-nitrophenyl diphenyl phosphate (p-NPDPP) is effectively catalyzed by micelles of [5-[(cr-N-~-histidinyl methyl ester) carbonyl] n-heptadecylltrimethylammonium chloride (1) and dimethylhexa-decyl [(4-imidazolyl) methyl] a" onium chloride (2) by factors of 95 and 400, respectively, at pH ca. 8. The kinetic solvent-deuterium isotope effects kH20/kD20 of 2-2.8 are consistent with imidazole moieties of the surfactants acting as ...
