In order to study the effect of ion pairing on nucleophilic reactivity and to help determine the sequence of nucleophilicity of the halide anions, the kinetics of displacement reaction between p-nitrobenzyl bromide and ionophoric chlorides labeled with chlorine-36 was studied in liquid sulfur dioxide at 0 C. Potassium chloride, rubidium chloride, tetramethylammonium chloride and tetraethylammonium chloride were employed asionophores. The concentration of the ionophores except for potassium chloride was varied over a wide range in order to evaluate the kinetic role of ion pairing.
