    • Group 6 metal-carbene complexes exhibit at least one reversible (or quasi-reversible) oxidation wave, the Epa values ranging -0.10 to +1.07 V. For any particular substituent attached to the carbene carbon, the Epa values are not greatly influenced by the organic group. However, variations of the heteroatom attached to the carbene carbon causes an increase of the oxidation potentials N < S < O, which parallels the established order of decreasing donor strength of these groups with respect to the carbene carbon empty p orbital. The influence of steric effects in the oxidation potentials has been also studied in aryl and heteroaryl carbene complexes. In these cases the cyclic voltammograms show a noticeable increase in the E pa values in the more crowded compounds. Otherwise, by electrochemical reduction, alkoxy aryl carbene complexes and ψ-conjugated complexes, show a quasi-reversible wave with Epc values ranging, 1.60 to -1.25V. S
