Electron transfer properties of ReO(ECD)

The electron transfer properties of the complex, ReO(ECD), where H 2 ECD is N , N ′-1,2-ethylenediylbis- L -cysteine, diethyl ester, are reported. The results of this study will demonstrate that ReO(ECD) has an unusual reductive electron transfer mechanism, in that the addition of one electron to this complex results in the loss of H /sd from the ligand. This corresponds to the net loss of a proton (H + ) from the complex and hence the product of the reduction is the same as that obtained by the reaction of a base with ReO(ECD) to form [ReO(ECD)] − .
