Tungsten(VI) Chloride Usage And Synthesis

Description

Tungsten(VI) chloride, WCl6, is a dark violet blue species that exists as a volatile solid under standard conditions. It is an important starting reagent in the preparation of tungsten compounds. As a d0 ion, W(VI) forms diamagnetic derivatives. WCl6 is octahedral with equivalent W-Cl distances of 2.24-2.26 ? .

Chemical Properties

dark grey-violet crystalline powder. Tungsten(VI) chloride is a blue-black solid at room temperature. At lower temperatures, it turns into wine red. A red form of the compound can be formed by quickly condensing its vapor, which transforms to the blue-black form on gentle heating. It is easily hydrolyzed, even by moist air, giving the orange oxychlorides WOCl4 and WO2Cl2, and then, tungsten trioxide. WCl6 is soluble in carbon disulfide, carbon tetrachloride, and phosphorus oxychloride. Methylation with trimethylaluminum forms hexamethyl tungsten.

Uses

Precursor to tungsten-based carbenes which catalyze the olefin metathesis reactions of 1- and 2-octene.

Uses

A precursor to tungsten based carbenes.

Uses

It is a precursor for many tungsten compounds. It is used in tungsten plating, purification of tungsten, and olefin polymerization. It is also used as petroleum catalyst, and in intelligent glass. It can be used for deoxygenation of epoxides and as a reagent in organic synthesis.

Definition

ChEBI: Tungsten hexachloride is a tungsten coordination entity.

Preparation

WCl6 can be prepared by chlorinating tungsten metal in a sealed tube at 600℃.
W +3Cl2→WCl6

Reactions

The tungsten reagents were prepared from tungsten hexachloride (Tungsten(VI) Chloride) in three ways: (i) with butyllithium; (ii) with a lithium dispersion; and (iii) with lithium iodide. In each case the ratio of WCl6 to lithium reagent is important.

Flammability and Explosibility

Not classified

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.
