A process for the preparation of azide derivatives useful as drugs, perfumes or intermediates of dyes by reacting an alcohol derivative with di-p-nitrophenyl phosphorazidate in the presence of 1,8-diazabicyclo[5.4.0]-7-undecene.

direct C(sp3)–H azidation using iron or manganese catalysis and a nucleophilic azide source. All reagents are commercially available, the experimental procedure is simple, and we can use the C–H donor substrate as the limiting reagent, a challenge for many C–H azidation methods. Preliminary experiments are consistent with a hydrogen atom transfer (HAT)/radical ligand transfer (RLT) radical cascade mechanism
