| Abstract: | The reversible addition of carbon monoxide to Rh(DPE)2]+ has been studied by cyclic voltammetry. The greatest contribution of this technique is that the uptake and release of CO, occurring before electron transfer, can be characterized and their rates measured.The differences in the reversibility of the CO addition between this complex and the isoelectronic isostructural cobalt and iridium ones are compared. A suggestion is made on the possible relevance of kinetic factors in the release of the CO molecule. |
