Technology Process of tetrafluoro(thioxo)tungsten

There total 4 articles about tetrafluoro(thioxo)tungsten which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 79.3%

antimony(III) sulfide + tungsten(VI) fluoride (7783-82-6) → tungsten sulphide tetrafluoride (41831-80-5) + antimony(III) fluoride (7783-56-4)

Guidance literature:

In hydrogen fluoride; HF (liquid); (N2); distillation of HF to Sb2S3, addn. of WF6 at -196°C, warming to room temp., storage for 16 h (or 14 h); decantation and soln. cooling to -78°C, extn. (HF) from solid, washing of solid at room temp., decantation, evapn. under vacuum at -78°C, drying for 10 min at room temp.;

Reference yield: 1.0%

hexamethyldisilathiane (3385-94-2) + tungsten(VI) fluoride (7783-82-6) → tungsten sulphide tetrafluoride (41831-80-5) + tungsten oxide tetrafluoride (13520-79-1,52049-91-9)

Guidance literature:

In acetonitrile; byproducts: Me3SiF; 77 K to room temp.; decantation for obtaining the compd. in soln.;

Reference yield:

boron(III) sulfide + tungsten(VI) fluoride (7783-82-6) → tetrafluoro(sulfido)tungsten(VI) (41831-80-5)
