A mild and efficient method for preparation of azides from alcohols using acidic ionic liquid [H-NMP]HSO4

We report here an efficient method for the synthesis and characterization of [H-NMP]SO4 and its application as an efficient catalyst and solvent for preparation of azides from corresponding alcohols under mild conditions. This processor showed high chemoselectivity for conversion of various alcohols to their corresponding azides. (C) 2008 Elsevier Ltd. All rights reserved.
