Nitroxide Radicals. Part 21. Spontaneous Decomposition of N-Aryl 1- and 2-Naphthyl Nitroxides
N-Aryl 1-naphthyl nitroxides self-react in solution to give the corresponding secondary amines and N-aryl-1,4-naphthoquinone imines.When reaction at the 4-naphthyl position is hindered by substituents benzoquinone imines are also produced.N-Phenyl 2-naphthyl nitroxide under similar conditions gives the corresponding amine and 2-phenylamino-1,4-naphthoquinone via a 1,2-naphthoquinone imine N-oxide intermediate.

Reactivity and Structure of N-Phenylnaphth-1-ylamines and Related Compounds. Part 2. Unpaired Electron Distribution in Naphth-1-yl Phenyl Nitroxides
The e.s.r. spectra of a series of naphth-1-yl phenyl nitroxides have been interpreted with the aid of complementary n.m.r. measurements.McLachlan MO calculations on naphth-1-yl phenyl nitroxide gives values for the naphthyl proton coupling constants which are not in good agreement with the experimental ones.
