Oxidation of tris-(p-carboxyltetrathiaaryl)methyl radical EPRprobes: evidence for their oxidative decarboxylation and molecular origin of their specific ability to react with O2˙

Abstract

Tris-(p-carboxyltetrathiaaryl)methyl radical EPR probes are very efficiently oxidized by superoxide and alkylperoxyl radicals with selective formation of quinone-methide products; this should explain the previously reported specific measurement of O2˙ using these EPR probes.
