Iodine (I) fluorosulfonate , ISO ₃ F is a chemical compound from the group of fluorosulfonates with iodine .

Extraction and presentation

Like the other halogen fluorosulfonates, iodine (I) fluorosulfonate can be obtained from iodine and peroxydisulfuryl difluoride .

${\displaystyle {\ce {I2 + S2O6F2 -> 2 ISO3F}}}$

properties

The reaction with iodine at 85 ° C can turn iodine (I) fluorosulfate into triiodofluorosulfonate .

${\displaystyle \mathrm {I_{2}+ISO_{3}F\ {\xrightarrow {85\,{}^{\circ }C}}\ I_{3}SO_{3}F} }$

A solution in carbon tetrachloride results in iodine chloride , peroxydisulfuryl difluoride and phosgene .

${\displaystyle {\ce {2 ISO3F + CCl4 -> 2 ICl + S2O6F2 + COCl2}}}$

But instead of phosgene, carbon dioxide can also be produced.

${\displaystyle {\ce {4 ISO3F + CCl4 -> 4 ICl + 2 S2O6F2 + CO2}}}$
