Technology Process of Thionyl fluoride

There total 105 articles about Thionyl fluoride 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: 80.0%

thionyl chloride (7719-09-7) + fluorine (7782-41-4) → thionyl fluoride (7783-42-8)

Guidance literature:

In further solvent(s); fluorination (N2 carrier gas (ratio F/N2 1:5), -50°C, als solvent freon-11);

Reference yield: 49.0%

(1,2-dibromotrifluoroethyl)pentafluorosulfur(VI) (22687-88-3) → fluorosulfonyl fluoride (640723-20-2,2699-79-8,12769-73-2) + disulfur decafluoride (5714-22-7) + 1,2,2-tribromo-1,1,2-trifluoroethane (354-49-4) + silicon tetrafluoride (7783-61-1) + thionyl fluoride (7783-42-8)

Guidance literature:

Irradiation (UV/VIS); irradiated (Hanovia S 500 lamp) in silica ampule, 20 h, further products;

Reference yield: 47.0%

sulfur (10544-50-0) + potassium fluoride (7789-23-3) + trichloroisocyanuric acid (87-90-1) → fluorosulfonyl fluoride (640723-20-2,2699-79-8,12769-73-2) + pentafluorosulfanyl chloride (13780-57-9) + thionyl fluoride (7783-42-8)
