Questions And Answer

• description

  Tungsten hexacarbonyl is easily vaporized and decomposed by the electron beam — providing a convenient source of tungsten atoms. This product is widely used in electron beam-induced deposition processes, it is also used as a precursor to catalysts for alkene metathesis and to desulfurize organosulfur compounds. It is relatively air-stable, and it is sparingly soluble in non-polar organic solvents. W(CO)6 reactions begin with the displacement of some of its CO ligands. Similar to Mo(CO)6 in behavior, W(CO)6 typically forms compounds that are kinetically more robust. Synthesis of this product are reported (see the links below).;

• uses

  Tungsten hexacarbonyl, [W(CO)6] may be used as a precursor for the deposition of WO3-x films, which may be used as gas sensors for the detection of NO2.
  Precursor to a Fischer carbene complex which reduces Pd(II) to nanoparticulate Pd(0) that is catalytically active in Hiyama cross-coupling.;

• Reaction

  Volatile starting material used for the atomic layer deposition of tungsten oxide, tungsten nitride.
  Tungsten hexacarbonyl is used to produce tungsten coatings on base metals. This is done by deposition of the carbonyl on the metal surface, which decomposes to leave a tungsten coating. ;

• Preparation

  Tungsten hexacarbonyl is produced by heating tungsten metal with carbon monoxide at high pressure. Also, carbonyl can be prepared by reducing the tungsten hexachloride by heating with iron powder under carbon monoxide pressure. ;
