Compared　to　universal　radical　difunctionalizations　of　alkenes　that　are　performed　with　organic　solvents,　such　reactions　with　water　as　the　sole　solvent　are　rarely　reported.　Concerning　the　global　consensus　on　environmental　issues,　we　have　developed　herein　a　method　for　the　radical　oxyazidation　of　alkenes　in　pure　water.　This　reaction　allows　the　construction　of　C-N　and　C-O　bonds　in　a　one-pot　process.　Styrenes,　1,3-dienes,　and　unactivated　alkenes　react　smoothly　under　mild　and　environmentally　benign　conditions　to　afford　a　wide　scope　of　functionalized　azides　in　excellent　yields　and　selectivities.
