Abstract

Abstract Ethylate ion reduces ferricenium cation to ferrocene and forms the α-oxy-ethyl radical identified by means of a spin-trap. The same radical is seen when irradiating ethanol solutions of methylferrocene in an ESR spectrograph cell in the presence of traces of oxygen. Taking into account these results we propose a scheme for the photoinduced oscillatory process in alcohol solutions of methylferrocenes or methylferricenium salts.
