Simultaneous Ejection of Six Electrons at a Constant Potential by Hexakis(4-ferrocenylphenyl)benzene

Abstract

A simple synthesis of a dendritic hexaferrocenyl electron donor (5) is described in which six ferrocene moieties are connected at the vertices of the propeller of the hexaphenylbenzene core. The molecular structure of 5 is confirmed by X-ray crystallography. An electrochemical analysis along with redox titrations (which are tantamount to coulometry) confirmed that it ejects six electrons at a single potential. [structure: see text]

Ferrocenyl‐Substituted Metallacycles of Titanocenes: Oligocyclopentadienyl Complexes with Promising Properties

“…Similar attractive molecular structures are found in compounds like hexakis(4-ferrocenylphenyl)benzene (C 6 -(C 6 H 4 Fc) 6 ), hexakis(ferrocenylethynyl)benzene (C 6 (C CFc') 6 , Fc' = substituted ferrocenyl) and [(FeCp) 3 (trindenyl)]. [5] In 2011, super-crowded ferrocenyl-substituted five-membered heterocycles ( c C 4 Fc 4 X, X = O, S, NR) were added to this family of compounds. [6] Their interesting electronic properties were studied in detail by spectroelectrochemistry.…”

The synthesis and characterisation of novel ferrocenyl polyphenylenes

“…To expand the library of possible compounds, 1,2-bis( p-ferrocenylphenyl)acetylene was successfully synthesised (Scheme S1, ESI †) using a route that differs from that published by Rathore et al 17 and subsequently used in a [2 + 4] Diels-Alder cycloaddition with 9 to give tetra-ferrocenyl polyphenylene 12.…”

Ferrocenylsubstituierte Metallacyclen des Titanocens – Oligocyclopentadienylkomplexe mit vielversprechenden Eigenschaften

“…¾hnliche interessante Molekülstrukturen zeigen Verbindungen wie Hexakis(4-ferrocenylphenyl)benzol (C 6 (C 6 H 4 Fc) 6 ), Hexakis(ferrocenylethinyl)benzol (C 6 (C CFc') 6 , Fc' = substituiertes Ferrocenyl) und [(FeCp) 3 (trindenyl)]. [5] Perferrocenylsubstituierte fünf-gliedrige Heterocyclen ( c C 4 Fc 4 X; X = O, S, NR), die erstmals 2011 vorgestellt wurden, sind weitere Beispiele reizvoller Verbindungen. [6] Ihre interessanten elektronischen Eigenschaften wurden intensiv mittels spektroelektrochemischer Messungen untersucht.…”
