Generation of solutions of highly persistent radical cations by 4-tolylthallium(III) bis(trifluoroacetate) in 1,1,1,3,3,3-hexafluoropropan-2-ol

Abstract

4-Tolylthallium(III) bis(trifluoroacetate) acts as a one-electron oxidant toward aromatic substrates in trifluoroacetic acid or 1,1,1,3,3,3-hexafluoropropan-2-ol, the latter solvent giving radical cation solutions of uniquely high persistency at room temperature.
