摘要：

A ferrocene-substituted cobaltacyclopentadiene complex, C5H5(PPh3)[Co-CH=CFc-CFc=CH] (1, Fc = ferrocenyl) undergoes quasi-reversible two-step one-electron oxidation reactions in 0.1 mol dm-3 Bu4NClO4-CH2Cl2 at room temperature, while irreversible two-electron oxidation (ECE reaction) of C5H5(PPh3)[Co-CFc=CH-CH=CFc] 2 causes intramolecular addition of PPh3 fragments to the buta-1,3-dienediyl moiety, affording PhCFc=CH-CH=CFcPOPh2 7 and PhCFc=CH-CFc=CHPPh2 8.
