✦ Synopsis

The basis dehydrobrornination of p-substituted 2-phenylethyl bromides promoted by hydroxide ion has been studied in rnicelles of N-hexadecyl-N,N,N-trirnethylarnrnoniurn nitrate (CTANO?). The pseudophase ion exchange model can be adapted to explain the kinetic results a t low hydroxide ion concentration, i.e., less than 0.075 M of NaOH. At high hydroxide ion concentration in solution the applied model does not describe the kinetic results unless the empirical variations are applied for the mol ratio of reactive ion to micellar head group (01 and the binding constant of the organic reagent to the rnicelle (K, 1.
