Abstract
The synthesis of the first stable enol linked to a ferrocene redox centre is reported. After one-electron oxidation of this compound we receive a persistent radical cation that can be activated by a second one-electron oxidation step. The resulting enol dication undergoes rapid deprotonation to a diradical cation which finally furnishes two benzofurans as products. The mechanism of this reaction and the role of the ferrocene as a redox relay is discussed.
