Oxidation of tris-(p-carboxyltetrathiaaryl)methyl radical EPR probes: 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.
