dark grey-violet crystalline powder | [Uses]
A precursor to tungsten based carbenes. | [Uses]
Precursor to tungsten-based carbenes which catalyze the olefin metathesis reactions of 1- and 2-octene. | [Definition]
ChEBI: Tungsten hexachloride is a tungsten coordination entity. | [Purification Methods]
Sublime it in a stream of Cl2 in a high temperature furnace and collect it in a receiver cooled in a Dry Ice-acetone bath in an inert atmosphere because it is sensitive to moisture. It is soluble in CS2, CCl4, CHCl3, POCl3, *C6H6, pet ether and Me2CO. Its solutions decompose on standing. Good crystals can be obtained by heating WCl6 in CCl4 to 100o in a sealed tube, followed by slow cooling (tablets of four-sided prisms). Store it in a desiccator over H2SO4 in the dark.
