Cationic micelles speed addition of cyanideion to the 4 position of N-alkyl-3-carbomoylpyridinium bromide (alkyl = N-C12H25, N-C14H29, N-C16H33). At high concentration of cetyltrimethylammonium cyanide (CTACN) the reaction rates become almost independent of (CTACN) as substrate binding approaches completion. The rates of these reactions in 0.005 M Cn/sup -/ go through maxima with increasing concentration
