The reaction of alkenes with IPy2BF4 and Me3SiN3 under the influence of BF3.OEt2 provides a mild an efficient entry to vicinal azidoiodoalkanes. Besides the simplicity of the experimental protocol and the convenience found in the handling of the reagents, the use of stoichiometric amounts of the azide source is remarkable, and overrides the known and always troublesome dependence on large excesses of azide to accomplish this synthetically valuable transformation.
