Technology Process of imido-bis(sulfuric acid) fluoride chloride

There total 3 articles about imido-bis(sulfuric acid) fluoride chloride 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:

bis(chlorosulfonyl)amine (15873-42-4) + lithium fluoride (7789-24-4) → fluorosulfonyl radical (12159-89-6) + imido-bis(sulfuric acid) fluoride chloride (237763-01-8) + amidosulfuric acid fluoride (14986-54-0) + fluorosulfate(1-)

Guidance literature:

In nitromethane;

Reference yield:

thionyl chloride (7719-09-7) + fluorosulphonic acid (7789-21-1) + urea (57-13-6) → imido-bis(sulfuric acid) fluoride chloride (237763-01-8) + bis(fluorosulfonyl)amide (14984-73-7)

Guidance literature:

In thionyl chloride; under dry N2; urea placed into a flask and flask immersed to a cold water bath; thionyl chloride added; HSO3F added dropwise, then the flask fitted with a reflux condenser, connected to a CaCl2 drying tube; heated at110°C for 42 h; reaction mixture fractionally distilled under vacuum; main fraction collected in the range 45-65°C/650 Pa; mixture of HN(SO2F)2, HN(SO2Cl)(SO2F), HSO3F in a ratio of 2.9:2.3:1 according to (19)F-NMR;
