Tungsten(VI) Chloride Chemical Properties,Uses,Production
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
reaction suitability
reagent type: catalyst
core: tungsten
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.
