ferrocene

[′fer·ə‚sēn]
(organic chemistry)
(CH2)5Fe(CH2)5 Orange crystals that are soluble in ether, melting point 174°C; used as a combustion control additive in fuels, and for heat stabilization in greases and plastics.

Ferrocene

 

(also dicyclopentadienyliron), (C5H5)2Fe, an orange crystalline solid having a melting point of 173°–174°C that is readily soluble in organic solvents. First synthesized in 1951, ferrocene is a member of a large class of organometallic compounds known as metallocenes. The ferrocene molecule has the sandwich structure that is characteristic of the class:

Ferrocene undergoes substitution reactions to the cyclopentadienyl rings; in this sense, the compound is similar to benzene and other aromatic compounds. For example, it is alkylated and acylated in the Friedel-Crafts reaction, and it also undergoes mercuration and sulfonation. The compound is stable at temperatures up to 400°C when heated in the air; it is also stable in the presence of acids and alkalies. Ferrocene is obtained by heating cyclopentadiene (C5H6) with metallic iron and by the reaction of cyclopentadienylmagnesium bromide (C5H5MgBr) with ferrous chloride.
