The reaction of azideion with 2-chloro-3,5-dinitropyrldine, n-butyl-4-nitrobenzenesulfonate and n-butyl-4-bromobenzenesulfonate is catalyzed by cationic micelles of cetyltrimethylammonium salt (CTAX, X=Cl-, Br-, 0.5 SO=4, OMes, N-3) The second-order rate constants in the micellar pseudophase is smaller than that in water.
