以苯硫酚为还原剂,在绿色溶剂、室温下将ααα-三溴甲基酮类化合物还原成αα-二溴甲基酮类化合物.此反应适用于芳香族、脂肪族和杂环类ααα-三溴甲基酮类化合物,产率高达97%.进一步的机理研究表明,该反应是自由基反应.

关键词: 苯硫酚, α,α-二溴甲基酮, 绿色合成, 还原反应

α,α-Dibromomethyl ketones were synthesized with high yields through a thiophenol-promoted reduction of α,α,α-tribromomethyl ketones under mild conditions within one hour. A further mechanistic study showed that the reaction proceeded via a radical process. This is an example that uses thiophenol as the radical stimulator in the reduction of multi-halogenated compounds.

Key words: thiophenol, α,α-dibromomethyl ketones, green synthesis, reduction
