An　efficient　copper-catalyzed　synthesis　of　carbamoyl　azides　directly　from　aldehydes　has　been　developed.　Both　aromatic　aldehydes　and　aliphatic　aldehydes,　together　with　other　commercially　available　reactants,　can　be　used　as　substrates　in　this　radical　relay　reaction.　Broad　substrate　scope,　simple　operation,　readily　available　reagents,　and　good　functionality　tolerance　make　this　method　very　attractive.
