The kinetics of fluorination of the salts of dinitromethyl compounds by xenon difluoride in acetonitrile are described by an equation of overall second order and of first order in each reagent.The nature of the cation in the salt does not affect the reaction rate.The thermodynamic activation parameters of the process (ΔH298excit. 30-60 kJ/mole, ΔS298excit. -60 to -130 J/mole*deg) lie in the typical ranges for an SN2 reaction.

The rates of the reaction of xenon difluoride with the salts of ortho-,meta-, and para-substituted aryldinitromethanes in acetonitrile were measured by a spectrophotometric method.The relationship between the structure of the substrates and their reactivity toward xenon difluoride is described by LFE equation with the induction, resonance, and steric constants of the substituents as parameters.The rate constants of the fluorination of the series of dinitrocarbanions are proportional to their one-electron electrooxidation potentials.The pKa values of the conjugate CH acids can be used as a test for the reactivity of the anions of dinitromethyl compounds in fluorination with xenon difluoride.
