Ferrocene is an organometallic compound with the formula Fe(C 5 H 5) 2. The molecule is a complex consisting of two cyclopentadienyl rings sandwiching a central iron atom. It is an orange solid with a camphor-like odor that sublimes above room temperature, and is soluble in most organic solvents.
Ferrocenophanes, also called ansa ferrocenes (from ansa: handle in greek), are organometallic compounds which are derived from ferrocene. They are a subset of ansa-metallocenes in which the metal is iron. In this compound class, the cyclopentadienyl ligands of the ferrocene are connected by one or more bridging groups. This hinders the rotation ...
Since the early 1960s ferrocene has been gaining acceptance as the standard reference for nonaqueous work for a number of reasons, and in 1984, IUPAC recommended ferrocene (0/1+) as a standard redox couple. [8] The preparation of the QRE electrode is simple, allowing for a fresh reference to be prepared with each set of experiments.
Space-filling model of ferrocene, the archetypal sandwich compound. In organometallic chemistry, a sandwich compound is a chemical compound featuring a metal bound by haptic, covalent bonds to two arene (ring) ligands. The arenes have the formula C n H n, substituted derivatives (for example C n (CH 3) n) and heterocyclic derivatives (for ...
Ferrocene. The first metallocene to be classified was ferrocene, and was discovered simultaneously in 1951 by Kealy and Pauson, [2] and Miller et al. [3] Kealy and Pauson were attempting to synthesize fulvalene through the oxidation of a cyclopentadienyl salt with anhydrous FeCl 3 but obtained instead the substance C 10 H 10 Fe [2] At the same time, Miller et al reported the same iron product ...
By linking ferrocene units to small silicon-containing dendrimers, some of these first-type dendrimers can be made. [3] Dendritic macromolecules with peripheral ferrocene groups are usually synthesized by linking ferrocene to the core through olefin metathesis or hydrosilylation [1].
Polyferroccenes have attracted interest as high-refractive-index polymers, such as in antireflection coatings or for light-emitting diodes. [4] Poly(1,1'-ferrocene-silane)e, poly(1,1'-ferrocene-phosphane) and polyferrocenes with phenyl side chains are polymers with unusually high refractive index, with values in the refractive index of up to 1.74.
Iron shows the characteristic chemical properties of the transition metals, namely the ability to form variable oxidation states differing by steps of one and a very large coordination and organometallic chemistry: indeed, it was the discovery of an iron compound, ferrocene, that revolutionalized the latter field in the 1950s.
