Bromine (III) fluorosulfonate , Br (SO ₃ F) ₃ is the trivalent bromine compound from the group of fluorosulfonates .

Extraction and presentation

The compound is formed as a reaction product from bromine and peroxydisulfuryl difluoride .

${\displaystyle {\ce {Br2 + 3 S2O6F2 -> 2 Br(SO3F)3}}}$

properties

Bromine (III) fluorosulfonate is very hygroscopic and reacts exothermically with water .

${\displaystyle {\ce {4 Br(SO3F)3 + 6 H2O -> 2 Br2 + 3 O2 + 12 HSO3F}}}$

The monovalent bromine (I) fluorosulfonate can be formed by adding bromine to bromine (III) fluorosulfonate.

${\displaystyle {\ce {Br(SO3F)3 + Br2 -> 3 BrSO3F}}}$
