Abstract Alkenes and Glycals react with Mn(OAc3)·2H2O and NaN3 in 9:1 acetonitrile-trifluoroacetic acid to give 1,2-diazides in >80% yield. Allylic azides are formed by slow addition of NaN3 to a mixture of alkene, Mn(OAc)3·2H2O and Cu(OAc)2.

A palladium‐catalyzedoxidative vicinal diazidation of alkenes has been developed, in which TMSN3 was used as azide source. Both styrenes and unactivated alkenes are suitable for this reaction. And trans‐alkyldiazides were obtained as major products from cyclic alkenes with moderate to good diastereoselectivities. This reaction afforded an efficient way for the synthesis of useful 1,2‐diamines after

synthetically valuable nitrogen‐containing building blocks which are difficult to obtain with alternative methods. Preliminary mechanisticstudies suggest that the reaction may proceed through a new mechanistic pathway in which both Lewisacid activation and iron‐enabled redox‐catalysis are crucial for selective azido‐group transfer.
