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
AbstractAn approach to the vicinal oxyazidation of alkenes has been achieved under mild and transition metal‐free conditions. This method utilizes NaN3 as the azidation agent and 2,2,6,6‐tetramethylpiperidine‐1‐oxoammonium tetrafluoroborate (TEMPO+BF4−) as the single‐electron oxidant as well as the oxygen source. By using this protocol, various β‐aminooxy azides were synthesized and several complex bioactive molecules were functionalized.magnified image
