Tetraelectronic process

However, electronic factors and/or the lack of suflflcient number of electrons could be limiting the tetraelectronic process, and the study of some peripherally... 

Many enzymatic oxidation processes proceed by a multielectron mechanism. For example, bielectron reduction of 02 to H202 and tetraelectron reduction to H20 produce short-lived... 

Typically, those ferrocenyl-porphyrins have been explored in photoinduced electron transfer and charge separation processes mimicking the activity of the photosynthetic system, as well as in the development of catalysts for multielectron transfer reactions. Ferrocenyl substituents were shown to enhance the electrocat-alytic activity of cobalt [41, 42], iron [43], and copper [44—46] porphyrins for tetraelectronic reduction of dioxygen to water.
