organoiron chemistry : ウィキペディア英語版 | organoiron chemistry Organoiron chemistry is the chemistry of iron compounds containing a carbon-to-iron chemical bond.〔''Synthesis of Organometallic Compounds: A Practical Guide'' Sanshiro Komiya Ed. S. Komiya, M. Hurano 1997〕〔''Iron-Catalyzed Reactions in Organic Synthesis''Carsten Bolm, Julien Legros, Jacques Le Paih, and Lorenzo Zani Chem. Rev. 2004, 104, 6217-6254 〕 Organoiron compounds are relevant in organic synthesis as reagents such as iron pentacarbonyl, diiron nonacarbonyl and disodium tetracarbonylferrate. Iron adopts oxidation states from Fe(-II) through to Fe(IV). Although iron is generally less active in many catalytic applications, it is less expensive and "greener" than other metals. Organoiron compounds feature a wide range of ligands that support the Fe-C bond; as with other organometals, these supporting ligands prominently include phosphines, carbon monoxide, and cyclopentadienyl, but hard ligands such as amines are employed as well. ==Alkyl and aryl compounds== The simple peralkyl and peraryl complexes of iron are far less developed than are the Cp and CO derivatives. Examples of compounds in this class are Fe(norbornyl)4 and tetramesityldiiron.
