A very low first oxidation potential (0.15 V vs SCE) characterizes the 12π‐electron title compound 1 , which is formed by reduction of the corresponding 14π‐electron system with potassium and trapping of the dianion with methyl iodide. Reaction of 1 with the electron acceptor 2 affords conducting charge‐transfer complexes (σ = 5.6 × 10 −2 S cm −1 ).
