Dielectric Breakdown of Silver Azide
The breakdown of single crystals of heavy metal azides has been investigated. In silver azide, the low-field conduction is by mobile interstitial cations and their enthalpies ,of formation and hopping have been determined from the Arrhenius plot of the conductivity. Based on AC conductivity · …

Synthesis of pyrrolizidine diols via azide-diene cycloadditions
The generality of the [4+1] annulation methodology in the context of natural product synthesis was demonstrated by extending its applicability to the heteroatom (nitrogen) case thus allowing access to the alkaloid field. This novel methodology involved the intramolecular union of a hypovalent …

Studies of sodium azide with tetraphenylcyclopentadienones and various analogs
The reaction of sodium azide with 2-p-chloro- and 2-p–methoxyphenyl–3,4,5-triphenyl–2,4-cyclopentadien– Iâ one was studied to determine if the substituent would have any appreciable effect on the product distribution of the corresponding …

The thermal decomposition of unirradiated and irradiated lithium azide
The thermal decomposition in vacuo of lithium azide, in powder and pellet form, has been investigated. The temperature range was 160° - 220° C. The results obtained were highly reproducible, and a study of the reaction kinetics was made for both the pelleted and powdered forms of the azide. …

Synthesis of 4-Azidocoumarins and Their Use in Copper-Catalyzed Azide-Alkyne Cycloaddition reactions
… to the 4-azidocoumarins by reaction with sodium azide (NaN3), and the overall process was simplified to a one-pot, two-step process. The methodology reduced the need for additional manipulations and purifications. Using the 4-azidocoumarins thus prepared, the 1,4-disubstituted-1,2,3 triazoles …
