A mild and clean synthesis of alkyl azides from alkyl halides mediated by poly(4-vinylpyridine)-supported sodium azide under nonaqueous conditions

Authors


Abstract

Alkyl halides were efficiently converted to their corresponding alkyl azides under mild nonaqueous conditions with a polymer-supported azide as a new polymeric reagent at room temperature at high yields and purities. All of the byproducts were removed by filtration, and pure products were obtained by the evaporation of the solvent. The spent polymeric reagent could usually be removed quantitatively and regenerated. The regenerated polymeric reagent could be reused several times. © 2011 Wiley Periodicals, Inc.
