|Section2= |Section3= |Section7= |Section8= }} Thionyl bromide is the chemical compound SOBr2. It is less stable and less widely used than its chloride analogue, thionyl chloride. It is prepared by the action of hydrogen bromide on thionyl chloride, a characteristic reaction where a stronger acid is converted to a weaker acid: :SOCl2 + 2HBr → SOBr2 + 2HCl Thionyl bromide is used for some brominations of certain α,β-unsaturated carbonyls, and it also converts alcohols to alkyl bromides. Otherwise it hydrolyzes readily to release sulfur dioxide: :SOBr2 + H2O → SO2 + 2HBr ==Safety== SOBr2 hydrolyzes readily to release dangerous HBr and acts as a lachrymator. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Thionyl bromide」の詳細全文を読む スポンサード リンク
