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.
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).

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.

Nozaki’s ferrocene derivative provided products that were only 86% optically pure. Ugi, et al. improved the stereoselectivity by using [1-(dimethylamino)ethyl]-ferrocene, providing products that had an optical purity >95%. The utility of Ugi’s amine in forming ligands for asymmetric catalysis was first reported in 1974 by Kumada, et al. [6]
Cyclopentadienyl magnesium bromide undergoes a complex reaction with iron(III) chloride, resulting in ferrocene: [31] 3 C 5 H 5 MgBr + FeCl 3 → Fe(C 5 H 5) 2 + 1/n (C 5 H 5) n + 3 MgBrCl. This conversion, although not of practical value, was important in the history of organometallic chemistry where ferrocene is emblematic of the field. [32]
Instead, the concentration should simply be given in units of g/mL. Percent solution or percentage solution are thus terms best reserved for mass percent solutions (m/m, m%, or mass solute/mass total solution after mixing), or volume percent solutions (v/v, v%, or volume solute per volume of total solution after mixing).
