title: TEMPO reacts with oxygen-centered radicals under acidic conditions.
abstract: In the presence of organic acids in organic media, 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) reacts with peroxyl radicals at nearly diffusion-controlled rates by proton-coupled electron transfer from the protonated nitroxide.
