diazidation method previously developed by us. This method effectively addresses the limitations of the existing olefin diazidation methods. Most notably, previously problematic nonproductive oxidant decomposition can be minimized. Furthermore, X-raycrystallographicstudies suggest that an iron–azide–ligand complex can be generated in situ from an iron acetate precatalyst and that it may facilitate peroxyester
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
