摘要：
The oxidation of Fc(C2H5)2, Fc(COCH3)2, and Fc(PPh2)2, where Fc is a ferrocene, with hydrogen peroxide in aprotic (dioxane and acetonitrile) and hydroxyl-containing (ethanol, acetonitrile–water, and water) solvents is studied via electron spectroscopy. The reactivity of these metal complexes relative to an oxidant is due to the electron-donor or electron-acceptor properties of substituents, their sizes, and their capability for the specific solvation by a particular solvent. Possible mechanisms of the oxidation of metal complexes are discussed. When Fc(PPh2)2 is oxidized, the formation of ferrocenyl cation Fc+(PPh2)2 is due to the redox isomerism of ferrocenylphosphonium cation Fc(PPh2)P+Ph2, which can form during the reaction between protonated complex Fc(PPh2)P(H+)Ph2 and H2O2.
