Abstract: Electrochemistry of nine kinds of bridging dinners of alkylferrocene derivatives was investigated in this article. It was found that CV waves of complexes showed only one reversible oxidation peak when the bridging group was -CH₂-. Other complexes give two reversible one-electron oxidation peaks. The only one oxidation potentials of the complexes dependent on the numbers of carbons y in substituent CyH_2y+1, and increase with y. But for the complexes of two oxidations peaks, the first potentials E_p1for oxidations were nearly constant when the bridging groups were the same, however, the second potentials E_p2slightly increase with the increase of y. According to the experimental results of burning rate catalytic activity, the smaller E_p2of complex, the larger its catalytic activity.
