Visible-Light Driven\nSynthesis of Vinyl Amines without\nPhotocatalyst

We developed a visible-light-induced vinyl amination\nof activated\nalkenes using TMSN<sub>3</sub> and CsF through EDA complex formation\nunder an oxygen atmosphere. Without light, the EDA complex forms between\nactivated alkene, CsF, and oxygen. Upon exposure to light, oxygen\nin the complex gets excited, initiating the HAT process. This method\nefficiently synthesizes vinyl-amine derivatives via a radical pathway,\ndemonstrating good functional group tolerance and high yields in a\nshort time. Further, the late-stage functionalization enables the\nsynthesis of biologically active heterocycles.
