Aromatic nucleophilic exchange reactions. Part III. Dipolar aprotic solvent effects
Abstract
Rates of halogen exchange between potassium iodide and 1-iodo-2,4-dinitrobenzene have been measured in six dipolar aprotic solvents and the results compared with those obtained in methanol. The effect of changing from methanol to a dipolar aprotic solvent is interpreted in terms of an initial state entropy change.
