AbstractThe bimolecular rate constants for the self-reaction of diethyl nitroxide radicals have been measured in water, methanol, n-propyl alcohol, benzene, CF2Cl2, and isopentane by epr spectroscopy. Activation parameters for the reaction were obtained in the last five named solvents. A reaction mechanism involving the reversible formation of a diamagnetic dimer and its slow decomposition to diethylhydroxylamine and a nitrone is proposed. Strong evidence for dimer formation has been obtained at low temperatures in CF2Cl2 and in isopentane.
