Bromine perchlorate is an inorganic chemical compound with the formula Br Cl O ₄. Its structure is Br−O−ClO₃. It is a shock and light-sensitive red liquid which decomposes above −20 °C. ^{[1] [2]}

Preparation and reactions

Bromine perchlorate can be produced from the reaction of cesium perchlorate and bromine fluorosulfate at −20 °C: ^[1]

CsClO₄ + BrSO₃F → BrOClO₃ + CsSO₃F

Alternatively, it can also be produced by the reaction of chlorine perchlorate and bromine at -45 °C. Bromine perchlorate reacts with hydrogen bromide to regenerate bromine: ^[1]

BrOClO₃ + HBr → Br₂ + HClO₄

This compound also reacts with cesium perchlorate, to produce Cs⁺[Br(ClO₄)₂]⁻ (caesium diperchloratobromate(I)), and various fluorocarbon halides, to produce fluoroalkyl perchlorates. ^{[3] [4]}
