Specific Features of the Oxidation of Ferrocenylacetic Acid and 1,1'-Diethylferrocene with Molecular Oxygen in Organic Solvents

摘要

Ferrocene (1, L_nM) is known to be very resistant to oxygen.Its oxidation occurs only in the presence of strong Bronsted acids,as a rule in aqueous-alcoholic medium [1-3].We were the first to establish on a quantitative level that the reactivity of ferrocene with respect to oxygen considerably increases on introduction into the cyclopentadienyl ligand of both electron-donor and electron-acceptor substituents having acidic moieties.
