Iron‐Catalyzed Azidoalkylthiation of Alkenes with Trimethylsilyl Azide and 1‐(Alkylthio)pyrrolidine‐2,5‐diones

Abstract A simple, efficient and practical iron‐catalyzed azidoarylthiation of alkenes has been developed at room temperature, and the corresponding products containing ortho ‐sited sulfide and azide units were obtained in moderate to good yields with good tolerance of functional groups. The protocol uses readily available 1‐(alkylthio)pyrrolidine‐2,5‐diones and trimethylsilyl azide as the alkylthiation and azidation reagents, respectively, inexpensive and environmentally friendly iron chloride as the catalyst without addition of any ligand and additive. magnified image
