• 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).

• synthetische

  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

• Definition

• Vorbereitung Methode

  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.

• Allgemeine Beschreibung

• Air & Water Reaktionen

  Sensitive to prolonged exposure to air and may be sensitive to light. Insoluble in water.

• läuterung methode

  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.
  

• Inkompatibilitäten

  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.
