Quantitative treatment of bromide ion nucleophilicity in a microemulsion

The reaction of p-bromphenacylmethyl picryl ether with bromide ion was followed in a microemulsion of cetyltrimethylammonium bromide (CTABr), n-octane, and n-butyl or tert-amyl alcohol. The second-order rate constants in the microemulsion droplets were estimated from the concentration of Br- in the droplets determined electrochemically. These rate constants are insensitive to the composition of the microemulsion, are similar to those in CTABr micelles in water and in aqueous n-butyl, n-hexyl, and tert-amyl alcohol, and are slightly higher than those estimated for the reaction in water. They are smaller than rate constants in the water-alcohol mixtures of relatively low water content. 37 references.
