aromatic amines, anilines and tertiary amines with dimethyldioxirane (DMD) was examined. Treatment of heterocyclic aromatic amines and anilines with a slight excess of DMD at 0 °C afforded the corresponding N-oxides in quantitative conversion yields. In addition, the oxidation was chemoselective in the presence of carbon-carbon double bonds. On the other hand, most of the tertiary amines assayed did
检查了杂环芳族胺,苯胺和叔胺与二甲基二环氧乙烷(DMD)的反应。在0℃下用稍微过量的DMD处理杂环芳族胺和苯胺,以定量转化率得到相应的N-氧化物。另外,在碳-碳双键的存在下,氧化是化学选择性的。另一方面,尽管反应条件,特别是有关所需DMD的量,取决于每种底物,但大多数测定的叔胺的确也提供了相应的N-氧化物的定量产率。在选定的底物上进行的其他研究表明,某些源自叔胺的N-氧化物会使DMD失活。
