In-situ electrochemical ESR the oxidation of triphenylacetic acid in acetonitrile

Abstract:

The oxidation of triphenylacetic acid in acetonitrile on platinum electrodes at + 1.94 V (vs. SCE) results in the formation of triphenylmethylcarbonium ions. If the potential is subsequently stepped to values negative of the Φ3C+/Φ3C· standard electrode potential (+0.25 V vs. SCE), reduction to the triphenylmethyl radical is seen. In rigorously anhydrous conditions no radicals other than Φ3C. can be detected by ESR. However in moist acetonitrile, oxidation at +1.94 V followed by reduction at ...
