The photochemistry of azidopyridine 1-oxides was studied using an array of glass and matrix isolation techniques. As with room temperature, the photochemistry of 4-azidopyridine 1-oxide is dominated by triplet nitrene chemistry. However, in the case of the 3-azide, matrix photolysis indicates the formation of diazabicyclo[4.1.0]hepta-2,4,6-triene N-oxide and diazacycloheptatetraene N-oxide intermediates as well as triplet nitrene.
利用一系列玻璃和基质隔离技术研究了叠氮吡啶1-氧化物的光化学。与室温情况一样,4-叠氮吡啶1-氧化物的光化学主要由三重态氮烯化学主导。然而,对于3-叠氮化物,基质光解表明形成了二氮杂双环[4.1.0]庚-2,4,6-三烯N-氧化物和二氮杂环庚四烯N-氧化物中间体以及三重态氮烯。
