Abstract
Low temperature spectroelectrochemistry was performed to generate highly reduced σ‐alkyl iron porphyrins, which were unstable at room temperature and oxygen sensitive. Suitable conditions for obtaining a stable compound were provided by keeping the thin‐layer cell under strictly anaerobic conditions. To calibrate the cell and check the deoxygenation the electrochemically produced radical anion of ZnTPP was used as an oxygen probe. By satisfying the anaerobic conditions, mainly due to the fact that no Teflon or Kel F spacers were used, it was possible for the first time to generate and characterize highly reduced σ‐alkyl iron porphyrins at low temperatures. The ligation reactions of these species were also stabilized.
