4-Azidoquinoline (VII) and its N-oxide (IV) were prepared from the corresponding hydrazino compounds (VI and III) with sodium nitrite and also from chloro compounds (II) with sodium azide. Similarly, 4-azidopyridine 1-oxide and 4-azido-2-picoline were obtained. The addition reaction of their azido group to propargyl alcohol, photolysis, and thermal decomposition were examined.
