Radical anion: Polycyclic radical anions, Other examples & Reactions

In organic chemistry, a radical anion is a free radical species that carries a negative charge. Radical anions are encountered in organic chemistry as reduced derivatives of polycyclic aromatic compounds, e.g. sodium naphthalenide. An example of a non-carbon radical anion is the superoxide anion, formed by transfer of one electron to an oxygen molecule.…
