Reactivity of an Aromatic σ,σ,σ‐Triradical: The 2,4,6‐Tridehydropyridinium Cation

Tri-, bi-, and monoradicals: The reactivity of a σ,σ,σ-triradical, 2,4,6-tridehydropyridinium cation, was compared with that of related mono- and biradicals in a Fourier transform ion cyclotron resonance mass spectrometer. The triradical has a doublet ground state and contains three interacting radical sites. The reactivity of the triradical more closely resembles that of related monoradicals than related biradicals.
