An improved protocol for the synthesis of alkyl or acyl azides by using [bmim]BF4 or [bmim]PF6 at ambient temperature under solvent free and neutral condition

Author(s): Atul Manvar, Dinesh Manvar, Nikhil Vekariya, Rupesh Khunt1, Anamik Shah

The present investigation deals with the synthesis of alkyl or acyl azides fromthe corresponding halo congeners employing roomtemperature ionic liquids 1-butyl-3-methylimidazoliumtetrafluoroborate[Bmim]BF4 or 1-Butyl- 3-methylimidazolium hexafluorophosphate[Bmim]PF6 as solvents at ambient temperature.Moreover, [Bmim]BF4 or [Bmim]PF6 can be recycled up to three runs without remarkable yield loss.
