Abstract

Azides 1 are important functional groups in organic synthesis for many purposes and have been extensively used for the introduction of amino groups and construction of heterocycles. 2 Aliphatic azides are usually prepared by nucleophilic substitution of the corresponding halides or sulfonates by azide ion. [3] and [4] Due to the advantageous and attractive strategy of the direct synthesis of azides from alcohols, some limited methods have been developed. Along this line, ...
