Abstract

The electrochemical behavior of Co₂(CO)₆(ethynylestradiol) complexes has been reinvestigated by means of electrochemical and spectroscopic techniques. The electrogenerated [Co₂(CO)₆(ethynylestradiol)]^- monoanion is very unstable and undergoes fast cleavage of the C–Co bond, producing Co(CO)₄^-. An efficient recombination Co(CO)4^• radical (produced from reoxidation of Co(CO)₄^-) with the [Co(CO)₂(ethynylestradiol)]^• radical, adsorbed on the electrode, regenerates almost qualitatively the parent complex, in the chemical time scale.
