Properties | Dibromosulfoxide is also called dibromothionyl, orange to yellow liquid. Melting point -52 ℃, boiling point 138 ℃(1.03 × 105Pa), 68 ℃(5.33 × 103Pa). Soluble in benzene, chloroform, carbon disulfide and carbon tetrachloride, etc., and decompose in water. |
Use | Dibromosulfoxide is a bromide and can be used as a brominating reagent. |
Preparation | Dibromosulfoxide is obtained by reacting hydrogen bromide and dichlorosulfoxide at 0°C for 12 hours, and can be quantified by vacuum distillation. |
