25127-53-1

WSCl4, or tungsten tetrachloride, is a chemical compound with the formula WCl4. It is a colorless, volatile, and moisture-sensitive solid that is highly soluble in organic solvents. WSCl4 is a significant precursor in the production of various tungsten compounds, including tungsten metal, tungsten carbide, and tungsten oxides. It is also used as a catalyst in certain chemical reactions and as a reagent in the synthesis of other tungsten-containing materials. WSCl4 is typically synthesized by reacting tungsten with chlorine gas or by the chlorination of other tungsten compounds. Due to its reactivity with water, it is essential to handle WSCl4 under anhydrous conditions to prevent hydrolysis.

25127-53-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25127-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,2 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25127-53:
(7*2)+(6*5)+(5*1)+(4*2)+(3*7)+(2*5)+(1*3)=91
91 % 10 = 1
So 25127-53-1 is a valid CAS Registry Number.

Reactions of Organosulphur Ligands on Tungsten Centres. Evidence for Carbonium Ion Formation in the Degradation of Alkanethiolatopentachlorotungsten(VI) Species

Boorman, P. Michael,O'Dell, Brenda D.

, p. 257 - 261 (2007/10/02)

The monothiolate derivatives of tungsten(VI) chloride, (R=Me, Et, cyclohexyl, Bui, But, CH2Ph, or Ph), have been found to be unstable with respect to at least two modes of degradation.Heterolytic cleavage of the carbon-sulphur bond to generate a carbonium ion, which can further abstract chloride to give WSCl4 + RCl, is the preferred pathway if the R(+) ion is relatively stable.The intermolecular elimination of R2S2 is the alternative route for degradation and is the exclusive one for R=Ph, where the carbonium ion is very unstable.The only pure compounds which have been isolated are and and even these slowly decompose at room temperature over a period of a few weeks.
