芳香杂环Ｎ－氧化物的化学，近年来在世界各国有了不少的发展，其重要性正在日益增 加。本文从Ｎ－氧化物的制法及其化学性质两方面，简单介绍了迭一领域的成就。同时，也 提出了作者企图研究α－与γ－甲基氮苯，α－与γ－甲基氮萘等杂环Ｎ氧化物环上甲基氧原 子的活性。 Aromatic heterocyclic N-oxide chemistry, in recent years in various countries in the world have made considerable progress, its importance is increasing. This article briefly introduces the achievements in the field of Dietetics from the aspects of the preparation of N-oxides and their chemical properties. At the same time, the author also proposed that the author should study the activity of methyl oxygen atom on heterocyclic N-oxide ring such as α- and γ-methylbenzene, α- and γ-methylnaphthalene.
