Correction to “Metal-Free Homogeneous O₂ Reduction by an Iminium-Based Electrocatalyst”

In the Spectrochemical Conditions portion of Scheme 1, a duplicated reaction step was incorrectly inserted in the original published version. In the revised version, two equivalents of protonated superoxide, ^•O₂H, disproportionate into an equivalent each of H₂O₂ and O₂, as is described in the text. This change does not have any consequence on the original conclusions.
