• The potential-current relationships of DMF solutions of a series of iron–sulfur compounds have revealed that in the presence of clusters [Fe<SUB>4</SUB>S<SUB>4</SUB>(SR)<SUB>4</SUB>]<SUP>2−</SUP> (R=PhCH<SUB>2</SUB> or Bu<I><SUP>t</SUP></I>) and [M<SUB>2</SUB>Fe<SUB>6</SUB>S<SUB>8</SUB>(SEt)<SUB>9</SUB>]<SUP>3−</SUP> (M=Mo or W) the electroreduction of CO<SUB>2</SUB> proceeds at the potential shifted by about 0.7 and 0.5 V, respectively, to the positive direction compared to the potential at which CO<SUB>2</SUB> is reduced without any catalyst. When controlled potential electrolysis of a DMF solution containing [Fe<SUB>4</SUB>S<SUB>4</SUB>(SCH<SUB>2</SUB>Ph)<SUB>4</SUB>]<SUP>2−</SUP> was carried out under CO<SUB>2</SUB> at −2.0 V vs. SCE, phenylacetate and formate were formed as the products resulting from CO<SUB>2</SUB> reduction. The cubane structure of this cluster collapsed rapidly under these conditions. However, when excess amount of PhCH<SUB>2</SUB>SH was added to the catholyte, the cluster structure was preserved during a relatively long period of electrolysis, and the yield of phenylacetate increased but that of formate decreased compared with the reaction in the absence of free PhCH<SUB>2</SUB>SH.
