Abstract A facile and efficient method was developed for the synthesis of vicinal azidoiodides in 62–77% yields by the reaction of sodium azide and iodine with unsaturated compounds in methanol, aqueous methanol, or the water–methanol–tetrahydrofuran solvent system. The reaction in Et2O or CHCl3 produced only vicinal diiodides.
monomer halogen, the need for in situ generation of unstable halogen azides (XN3), applicability to one type of haloazidation and inability to precisely control selectivity. Herein, we developed a universal strategy for haloazidation of alkenes through controlling the reactivity of IBA-N3 by switching halogen salts, allowing for the synthesis of a diversity of halogen azide products.
