We report the observation of the electrochemically generated nitrenium ions of 4,4'-dimethyoxydiphenylamine and di- p -tolylamine in solution by mass spectrometry. This setup takes inspiration from desorption electrospray ionization mass spectrometry to sample directly from the surface of a rotating waterwheel working electrode for mass spectrometric analysis. Detection of the 4,4'-dimethyoxydiphenylamine nitrenium ion was expected based upon para -methoxy resonance stabilization, whereas observation of the di- p -tolylamine nitrenium ion might be unexpected because resonance stabilization from the para -substituted position is unavailable. However, the short timescale analysis of the setup allows for the isolation of the di- p -tolylamine nitrenium ion, which is electrogenerated in solution and detected mass spectrometrically.
