Rapid Synthesis of Aryl Azides from Aryl Halides under Mild Conditions

Abstract A rapid synthesis of aryl azides from the corresponding aryl halides catalyzed by CuI/diamine is described. Sodium ascorbate was found to have a positive effect on stabilization of the catalyst system. The reactions were performed under very mild conditions generally with high yields. In the case of aryl iodides, the transformation could be carried out at room temperature.
