Trifluorosulfonium fluorosulfate, with the chemical formula (FSO2)2NF2, is a highly reactive and powerful fluorinating agent. It is a colorless, crystalline solid that is soluble in polar solvents such as water and acetonitrile. trifluorosulfonium fluorosulfate is formed by the reaction of trifluorosulfur dioxide (FSO2F) with nitrogen trifluoride (NF3). Trifluorosulfonium fluorosulfate is known for its ability to transfer fluorine atoms to various substrates, making it a valuable reagent in organic and inorganic chemistry for the synthesis of fluorinated compounds. Due to its high reactivity, it is typically handled with caution and under controlled conditions to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 88548-61-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,5,4 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88548-61:
(7*8)+(6*8)+(5*5)+(4*4)+(3*8)+(2*6)+(1*1)=182
182 % 10 = 2
So 88548-61-2 is a valid CAS Registry Number.

Some reactions of sulfonyl hypohalites with sulfur tetrafluoride

O'Brien, Brian A.,DesMarteau, Darryl D.

, p. 644 - 648 (2008/10/08)

The reactions of ClOSO2F, BrOSO2F, and ClOSO2CF3 with SF4 have been investigated. It has been found that the reactions proceed to form either trifluorosulfonium salts or covalent adducts. In the cases where the hypochlorites were used, the unusual cation SF4Cl+ can be postulated as a reactive intermediate. Characterizations of the new compounds SF3+FSO3-, SF3+CF3SO3-, cis-SF4(Cl)OSO2F, trans-SF4(Cl)OSO2F, and trans-SF4(Cl)OSO2CF3 are reported. The SF3+ salts are thermally unstable, decomposing to SF4, SOF2, and (XSO2)2O (X = F, CF3).
