The formation of thiyl radicals from [Cp^*Ru^III{κ³<i>SSSi>′-tpdt}] (1A) and [Cp^*Ru^III{κ³<i>SSNi>-apdt}] (1B) {Cp^* = η⁵-C₅Me₅; tpdt = S(CH₂CH₂S⁻)₂; apdt = HN(CH₂CH₂S⁻)₂} has been initiated by thiolate alkylation or oxidation with iodine. Subsequent electron transfer processes yielded disulfide-bridged dinuclear complexes. The mechanistic pathways of these processes will be discussed.
