The dicyanomethylene group and not the quinone oxygen atoms is the site of the first one‐electron reduction for the dicyanohetereotriquinone methide 1 , although the dicyanomethylene group is substituted at a cyclopentadienyl‐like five‐membered ring! Compound 1 is amphoteric and undergoes a five‐stage sequence of one‐electron redox reactions.
