摘要：
The metal complex in the FcCH(2)OH-HClO4-p-benzoquinone system is oxidized with p-benzoquinone as well as with the hydrogen ion as a result of its protonation. Involvement of the acid in both processes determines their influence of each of them on the rate of the other one. This fact has been confirmed by the obtained dependences of the rate of ferrocenium ions accumulation during protonation and oxidation of FcCH(2)OH on the reactants concentrations as well as by the derived kinetic equations of the processes. The degree of their mutual influence depends on the solvating properties of the solvents and the ratio of the starting concentrations of the metal complex and the acid, which affect the yield of the FcC(+)H(2) carbocation and its ability to redox isomerism upon protonation of the metal complex.
