Various primary and secondary alkyl azides have been synthesized in high yields by the fluoride anion induced SN2 substitution reactions of the corresponding alkyl halides, phosphates, or tosylates and trimethylsilyl azide.

Trialkylboranes prepared from alkenes via hydroboration react with lead(IV) acetate azide in dichloromethane at −25 °C to form the corresponding azidoalkanes in a one-pot manner. One or two of the alkyl groups of trialkylboranes are utilized in the reaction. For example, 1-azidohexane is afforded from 1-hexene in 50% yield based on the alkene employed.

A convenient procedure was developed for the synthesis of 2-azidobicyclo[2.2.1]heptane whose click reaction with phenylacetylene afforded 1-(bicyclo[2.2.1]heptan-2-yl)-4-phenyl-1H-1,2,3-triazol, and its reactions with ethyl α-bromoacrylate and ethyl acetoacetate gave 1-(bicyclo[2.2.1]heptan-2-yl)-5-R-1H-1,2,3-triazole-4-carboxylic acids.
