Ferrocene Chemical Properties,Uses,Production
Organic transition metal
Ferrocene is an organic transition metal compound that has aromatic properties and is also known as dicyclopentadienyl iron. Its molecular structure contains a divalent iron cation and two cyclopentadienyl anions. It is used as a raw material in the production of ferrocenecarboxylic acid and was first successfully produced in the 1950s by reacting cyclopentadienyl magnesium bromide with anhydrous ferric chloride. Ferrocene is a non-polar compound that appears as an orange needle crystal powder with a camphor-like smell at room temperature. It is soluble in many organic solvents, including methanol, ethanol, ethyl ether, petroleum ether, gasoline, kerosene, diesel oil, methylene chloride, benzene, toluene, and xylene. Ferrocene has a molecule with polarity, high thermal stability, chemical stability, and radiation resistance, making it useful in industry, agriculture, medicine, aerospace, energy, environmental protection, and other fields.
Chemical Properties
Ferrocene is a crystal with orange needle-like structure that sublimates at temperatures higher than 100℃ and melts at 172.5-173℃. Its boiling point is 249℃. It is soluble in dilute nitric acid, concentrated sulfuric acid, benzene, ether, petroleum ether and tetrahydrofuran and generates bluish fluorescence-containing deep red solution in dilute nitric acid and concentrated sulfuric acid. It is insoluble in water, 10% sodium hydroxide and hot concentrated hydrochloric acid, and it remains stable in air. Ferrocene has a strong property of UV absorbing and great thermostability, withstanding heating up to 470℃. It has a camphor-like scent and can be evaporated with water vapor. Ferrocene is neither dissolved nor decomposed in boiling solutions of these solvents.
Uses
Ferrocene and its derivatives have various applications in different fields. It can be used as additives in rocket fuel, antiknock agent in gasoline, curing agent in rubber and silicone resin, and ultraviolet absorber.

Preparation
Dicyclopentadienyliron may be obtained in a single-step synthetic route by heating cyclopentadiene with iron or iron pentacarbonyl at 300°C:
2C5H5 + Fe → (C5H5)2Fe
Also, it can be prepared by the reaction of iron(II) chloride with cyclopentadiene in the presence of an alkyl amine or a similar base.
Another convenient method of preparing this π-complex of iron is a twostep process in which the first step involves preparation of cyclopentadienyl Grignard reagent, such as 2,4-cyclopentadienylmagnesium bromide C5H5MgBr which may then be combined with ferric chloride to yield dicyclopentadienyl iron:
3C5H5MgBr + FeCl3 → (C5H5)2Fe + 3MgBrCl
Another general method of preparation involves the reaction of cyclopentadiene with sodium metal or sodium hydride in tetrahydrofuran (THF). Addition of iron(II) chloride to this solution forms the complex dicyclopentadienyliron:
2C5H6 + 2Na → 2C5H5ˉ + 2Na+ + H2
In 3:2 molar ratio of cyclopentadiene to sodium cyclopentene is obtained along with cyclopentadienidide (C5H5ˉ ) anion:
3C5H6 + 2Na → 2C5H5¯ + 2Na+ + C5H8
FeCl2 + 2C5H6Na → (C5H5)2Fe + 2NaCl

A coordination compound of ferrous iron and two molecules of cyclopentadiene in which the organic portions have typically aromatic chemical properties. Its activity is intermediate between phenol and anisole. The first compound shown to have the “sandwich
Production Methods
Ferrocene is produced from the reaction of cyclopentadiene with reduced iron in the presence of metal oxides. There is also a two-stage production process in which produced iron (II)oxide (stage 1) is reacted with cyclopentadiene.
Definition
ferrocene: An orange-red crystallinesolid, Fe(C5H5)2; m.p. 173°C. Itcan be made by adding the ioniccompound Na+C5H5- (cyclopentadienylsodium, made from sodium andcyclopentadiene) to iron(III) chloride.In ferrocene, the two rings are parallel,with the iron ion sandwiched betweenthem (hence the namesandwich compound: see formula).The bonding is between pi orbitalson the rings and d-orbitals on theFe2+ ion. The compound can undergoelectrophilic substitution on theC5H5rings (they have some aromatic character).It can also be oxidized to theblue ion (C5H5)2Fe+. Ferrocene is the first of a class of similar complexescalled sandwich compounds. Its systematicname is di-π-cyclopentadienyliron(II).

Store in tightly closed containers in a cool,well-ventilated area away from oxidizers, ammonium perchlorate, tetranitromethane, mercury(II) nitrate, and heat.Sources of ignition, such as smoking and open flames, areprohibited where this chemical is used, handled, or stored ina manner that could create a potential fire or explosionhazard.
Shipping
UN1325 Flammable solids, organic, n.o.s., Hazard Class: 4.1; Labels: 4.1-Flammable solid.
Purification Methods
Purify it by crystallisation from pentane or cyclohexane (also *C6H6 or MeOH can be used). It is moderately soluble in Et2O and sublimes readily above 100o. Crystallisation from EtOH gave material m 172.5-173o. [Wilkinson Org Synth Coll Vol IV 473 1963, Miller J Chem Soc 632 1952.] It has also been crystallised from methanol and sublimed in vacuo. [Saltiel et al. J Am Chem Soc 109 1209 1987, Beilstein 16 IV 1783.]
Structure and conformation
X-ray diffraction studies show that in crystalline ferrocene (and in its
substituted derivatives) the iron atom is "sandwiched" between the two cyclopentadienyl
rings, these rings having the staggered configuration relative to each other (Fig. 16). The
rings are parallel plane regular pentagons, all the C-C and Fe-C distances being equal.
Electron diffraction studies show, however, that ferrocene has the eclipsed configuration
in the vapour state.
Incompatibilities
Violent reaction with ammonium per chlorate, tetranitromethane, mercury(II) nitrate. Incompa tible with oxidizers (chlorates, nitrates, peroxides, perman ganates, perchlorates, chlorine, bromine, fluorine, etc.);
contact may cause fires or explosions. Keep away from
alkaline materials, strong bases, strong acids, oxoacids,
epoxides.
Peroxomonosulfuric acid. Decomposes @≧465 ℃.
