Synthesis and Electrochemistry of 1,2,4-Triferrocenylbenzene

Abstract

1,2,4-Triferrocenylbenzene (TFB) was synthesized by the [Co₂(CO)₆(μ₂,h₂-ferrocenyl acetylene)]catalyzed cyclization reaction of ferrocenyl acetylene. The molecular structure of 1,2,4-triferrocenylbenzene was determined by X-ray single crystal diffraction. The position selectivity of ferrocenyl was interpreted by K-Hübel's mechanism. The electrode reaction behaviours were demonstrated by cyclic voltammetry and microelectrode chronoamperometry.
