摘要

Cyclic voltammetry of 1-nitroso-2-naphthol in the potential region 0 to 1.0 V vs Ag/AgCl using glassy carbon and platinum electrodes shows a reversible redox couple. The electrode process is diffusion controlled and corresponds to an EC mechanism. The one-electron oxidation product, an iminoxyl radical, is characterized by a triplet ESR signal at g = 2.0067 further split by three ring hydrogens. This radical is unusually long-lived, with half-life times of 150 s in water and 3600 s in acetonitrile.
