New solvent-free brominations of 1,3-dicarbonyl compounds, phenols, various alkenes including chalcones, azachalcones, 4-phenylbut-3-en-2-one, methyl cinnamate, styrene and 1,3-cyclohexadiene were efficiently achieved by employing sodium bromide and oxone under mechanical milling conditions. The brominated products were obtained in good to excellent yields.
在机械研磨条件下,通过使用溴化钠和过硫酸钾,成功高效地实现了1,3-二羰基化合物、酚类、包括查尔酮、氮查尔酮、4-苯基-3-丁烯-2-酮、肉桂酸甲酯、苯乙烯和1,3-环己二烯在内的各种烯烃的无溶剂溴化反应。所得到的溴化产物收率良好至优异。
