What are the applications of Application

Tungsten hexacarbonyl is A precursor to a Fischer carbene complex which reduces Pd(II) to a nanoparticulate Pd(0) that is catalytically active in Hiyama cross-coupling.(1)

General Description

Atomic number of base material: 74 Tungsten

Health Hazard

Toxicity of this compound is not reported.Although air stable at ambient temperature,upon heating it emits toxic carbonmonoxide. Chronic exposure to its vaporsor dusts can cause bronchitis. Ingestion islikely to produce the toxic effect of tungstenoxides.

Fire Hazard

It explodes when heated to high temperature. Solution in ether can explode if stored for a long time.

Purification Methods

Sublime it in vacuo before use [Connoe et al. J Chem Soc, Dalton Trans 511 1986]. TOXIC.
