azaheterocycle N-oxides with alkenes catalyzed by iodine under metal- and external oxidant-free reaction conditions has been developed. A variety of (E)-2-styrylazaheterocycles have been produced in moderate to excellent yields. The mechanistic exploration indicated that the N-oxide group played dual roles as both the directing group and an internal oxidant in this catalytic cycle.
在无金属和无外部氧化剂的反应条件下,开发了一种有效的且区域选择性的氮杂杂环N-氧化物与碘催化的烯烃的区域选择性烯基化方法。已经以中等至优异的产率生产了多种(E)-2-苯乙烯基杂氮杂杂环。机理探索表明,在该催化循环中,N-氧化物基团既充当导向基团又充当内部氧化剂。
