在无溶剂和室温条件下, 三溴化1-丁基-3-甲基咪唑([Bmim]Br3)选择性地与酮反应, 以90%～96%的产率生成相应的α-溴代酮. 该方法反应条件温和、产率高、选择性好、环境友好.

关键词: 脂肪酮, 离子液体, 溴化, 三溴化1-丁基-3-甲基咪唑

Reaction of ketones with 1-butyl-3-methylimidazolium tribromide ([Bmim]Br3) under solvent-free conditions at room temperature, selectively gave the corre-sponding α-bromoketones with 90%～96% yields. Compared to the known report, this method has the advantages of mild reaction condition, good yields, high selectivity and more environmental benignity.

Key words: ionic liquid, alkanone, 1-butyl-3-methylimidazolium tribromide, bromination
