Alkyl azides. Sodium azide as such is of little use for preparation of alkyl azides by nucleophilic substitution reactions because of solubility problems. The reaction can be carried out under phase-transfer conditions with methyltrioctylam-monium chloride/NaN3.3 An even more effective polymeric reagent can be obtained by reaction of NaN3 with Amberlite IR-400.4 This reagent converts alkyl bromides, iodides, or tosylates into azides at 20° in essentially quantitative yield. The solvents of choice are CH3CN, CHC13, ether, or DMF.

Most automobile airbags contain sodium azide (NaNj) as the propellant. When accelerometers detecta crash, the electronic controllerfiresthe charge of sodium azide. Sodium azide decomposes explosively, generating nitrogen gas that fills the airbag. 

Hazards Use proper ventilation and wear gloves when handling trioxane, 1,2-dichloroethane, and l,3-dichloro-2-propanol. Avoid inhalation of vapors. Use caution and wear gloves when handling 98% sulfuric and sodium azide. Sodium azide is highly toxic, and can be absorbed through the skin. 

Hazards Wear gloves and use proper ventilation when handling DMSO, and avoid inhalation of vapors. Wear gloves when handling sodium azide. Sodium azide is highly poisonous, and can be absorbed by the skin. 

The avidin-containing resin is stable to storage at 4°C for many years in the presence of azide. (Sodium azide is a potent poison and should be treated accordingly.) Biotinylated antibody (and other proteins) can also be stored almost indefinitely at -20°C. Thus, the preparation of the affinity resin C in be performed in several minutes.

Azides are salts of hydrazoic acid (N3H). Alkali metal azides are the most important intermediates in the production of -> Lead Azide. Sodium azide is formed by the reaction between sodium amide (NaNH2) and nitrous oxide (N20). Sodium amide is prepared by introducing gaseous ammonia into molten sodium. 

The two reaction pathways studied involve a route from the carboxylic acid to the isocyanate via the acyl chloride and azide (Sodium Azide Pathway, Pathway A), Figure 4 and a route from the carboxylic acid to the isocyanate via the hydrazide (Hydrazide Pathway, Pathway B), Figure 5. The reactions were monitored by isolating the intermediate reaction products and characterizing them by melting points, elemental composition, or IR spectroscopy. 

The cyclopropanone (65) on treatment with trimethylsilyl-azide, sodium azide and 15-crown-5 gives the azide (66), which is readily converted to the p-lactam (67) in high yield (93JCS(P1)1553).
