Nitrosyl fluorosulfonate , NOSO ₃ F is an inorganic compound of the nitrosyl cation NO ⁺ from the group of fluorosulfonates .

Extraction and presentation

The reaction of nitrogen dioxide and peroxydisulfuryl difluoride allows the salt to be synthesized.

${\displaystyle {\ce {2 NO2 + S2O6F2 -> NOSO3F + NO2SO3F + 1/2O2}}}$

Instead of NO ₂ it is possible to use nitrosyl nitrate for extraction.

${\displaystyle {\ce {NONO3 + S2O6F2 -> NOSO3F + NO2SO3F + 1/2O2}}}$

Nitrosyl fluorosulfonate can also be produced with dinitrogen trioxide and fluorosulfonic acid .

${\displaystyle {\ce {N2O3 + 2 HSO3F -> 2 NOSO3F + H2O}}}$
