Spectroelectrochemical investigation of the dicobalt complex 1 (M′ M″ Co II ), which was synthesized in only a few steps in good yield from simple starting materials, revealed the presence of the mixed‐valence Co II –Co I complex as well as the Co I –Co I complex. The UV/VIS spectrum and the ESR results for the mixed‐valence species indicate that the unpaired electron is delocalized. The electrocatalytic reduction of O 2 on carbon electrodes coated with 1 occurs at −0.34 V (vs. SCE). R CH 2 C(CH 3 ) 3 .
