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.
Acetylferrocene is prepared by Friedel-Crafts acylation of ferrocene, usually with acetic anhydride (Ac 2 O): . Fe(C 5 H 5) 2 + Ac 2 O → (C 5 H 5)Fe(C 5 H 4 Ac) + HOAc. The experiment is often conducted in the instructional laboratory to illustrate acylation as well as chromatographic separations.
Ferrocenecarboxaldehyde, owing to the versatility of the formyl group, is a precursor to many ferrocene-modified compounds. With a Wittig reagent, it converts to vinylferrocene and related derivatives. [5] With primary amines, ferrocenecarboxaldehyde condenses to give imines. The azomethine derivative undergoes 1,3-cycloaddition to C 60. [6]
Density: 1.862 g/cm 3 [1] Melting point: 214–216 °C (417–421 °F; 487–489 K) ... It is the simplest carboxylic acid derivative of ferrocene. It can be prepared ...
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 ...
1,1 ′-Bis(diphenylphosphino)ferrocene, commonly abbreviated dppf, is an organophosphorus compound commonly used as a ligand in homogeneous catalysis. It contains a ferrocene moiety in its backbone, and is related to other bridged diphosphines such as 1,2-bis(diphenylphosphino)ethane (dppe).
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.

N,N-Dimethylaminomethylferrocene is the dimethylaminomethyl derivative of ferrocene, (C 5 H 5)Fe(C 5 H 4 CH 2 N(CH 3) 2. It is an air-stable, dark-orange syrup that is soluble in common organic solvents. The compound is prepared by the reaction of ferrocene with formaldehyde and dimethylamine: [1] (C 5 H 5) 2 Fe + CH 2 O + HN(CH 3) 2 → (C 5 H ...
