Beschreibung

Anwendung

Precursor to a Fischer carbene complex which reduces Pd(II) to nanoparticulate Pd(0) that is catalytically active in Hiyama cross-coupling.

Tungsten hexacarbonyl, [W(CO)₆] may be used as a precursor for the deposition of WO_3-x films, which may be used as gas sensors for the detection of NO₂.
