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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
