  • Fe(CO)5 is produced by the reaction of fine iron particles with carbon monoxide. (wikipedia.org)
  • The monoanion is an intermediate in the homogeneous iron-carbonyl-catalyzedwater-gas shift reaction (WGSR). (wikipedia.org)
  • Ferrocene is formed by reaction of sodium cyclopentadienide with iron(II) chloride: 2 NaC5H5 + FeCl2 → Fe(C5H5)2 + 2 NaCl Ferrocene displays diverse reactivity localized on the cyclopentadienyl ligands, including Friedel-Crafts reactions and lithation. (wikipedia.org)
  • Aluminium tribromide reacts with carbon tetrachloride at 100 °C to form carbon tetrabromide: 4 AlBr3 + 3 CCl4 → 4 AlCl3 + 3 CBr4 and with phosgene yields carbonyl bromide and aluminium chlorobromide:[citation needed] AlBr3 + COCl2 → COBr2 + AlCl2Br Al2Br6 is used as a catalyst for the Friedel-Crafts alkylation reaction.

  • oxide
  • In 1934, BASF was also involved in the development of the very first magnetic tapes used by the AEG Magnetophon tape recorder: carbonyl iron became the first magnetic recording oxide (although quickly replaced in 1936 by iron oxide). (wikipedia.org)
  • Production soon moved to iron oxide coated onto cellulose acetate rolls cut into uniform strips wound onto plastic or metal hubs. (wikipedia.org)
  • Tape consists of a coating of a magnetic pigment, typically iron oxide (Fe2O3), on a long strip of polyester (polyethelyne terephthalate) base film. (wikipedia.org)
  • Sodium
  • Increasing the covalent character of the metal-oxygen bond (by, for instance, employing iron carbonyl reducing agents instead of sodium) also stabilizes the oxyallyl cation, leading to cleaner reactions. (wikipedia.org)
  • Ligands
  • Most metal carbonyls have 18 valence electrons, and Fe(CO)5 fits this pattern with 8 valence electrons on Fe and five pairs of electrons provided by the CO ligands. (wikipedia.org)
  • The nomenclature of the metal carbonyls depends on the charge of the complex, the number and type of central atoms, and the number and type of ligands and their binding modes. (wikipedia.org)
  • Infrared spectroscopy is a sensitive probe for the presence of bridging carbonyl ligands. (wikipedia.org)
  • tetracarbonyl hydride
  • Acidification of solutions of [HFe(CO) gives iron tetracarbonyl hydride, H2Fe(CO)4, the first metal hydride ever reported. (wikipedia.org)
  • Iron tetracarbonyl hydride is the organometallic compound with the formula H2Fe(CO)4. (wikipedia.org)
  • In iron tetracarbonyl hydride the Fe(CO)4 group has C2v molecular symmetry with a geometry intermediate between octahedral and tetrahedral. (wikipedia.org)
  • compound
  • Also known as tetracarbonyldihydridoiron, tetracarbonyldihydroiron, or iron tetracarbonyl dihydride, this compound was the first metal hydride discovered. (wikipedia.org)
  • oxygen
  • Iron is important for many functions in the body, especially for the transport of oxygen in the blood. (wellspan.org)
  • Complex
  • Here, we extend our previous studies by showing that η-4-(4-bromo-6-methyl-2-pyrone)tricarbonyl iron (0) (CORM-F3), an irontricarbonyl complex that contains a 2-pyrone motif, liberates CO in vitro and exerts pharmacological actions that are typical of CO gas. (aspetjournals.org)
  • As for Cooke's early discovery, an iron acyl complex undergoes protonolysis to give the aldehyde. (wikipedia.org)
  • Simple thermolysis, however, is not a useful synthesis, and each iron carbonyl complex exhibits distinct reactivity. (wikipedia.org)
  • The enone complex (benzylideneacetone)iron tricarbonyl serves as a source of the Fe(CO)3 subunit and is employed to prepare other derivatives. (wikipedia.org)
  • applications
