Tungsten hexacarbonyl
Synonym: Tungsten carbonyl, Hexacarbonyl wolfram, W(CO)6
CAS Number 14040-11-0 | MDL Number MFCD00011462 | EC Number 237-880-2
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).
