An environmentally benign, copper-catalyzed diazidation of a broad range of olefins, including vinylarenes, unactivated alkenes, allene, and dienes, under mild conditions with TMSN3 (trimethylazidosilane) as azido source, has been developed. This reaction can be carried out in organic solvent or in aqueous solution where water is the sole solvent. The functional group compatibility of this reaction

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.
A visible light-induced vicinal diazidation of various alkenes using stable sulfonium bis(acetoxy)iodate(I) and sodium azide as a radical precursor is described. The trimethylsulfonium [bis(azido)iodate(I)] species, intrinsically generated in situ, demonstrated unprecedented reactivity toward CC π bond-promoting selective azidation under photochemical conditions without any photoredox or metal catalyst
