The formation of thiyl radicals from [Cp*Ru-III{(KSSS)-S-3'-tpdt}] (1A) and [Cp*Ru-III{(KSSN)-S-3-apdt}] (1B) {Cp* = eta(5)-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. (C) 2007 Elsevier B.V. All rights reserved.
