Photoinduced Cross-Coupling Of Aryl Iodides With Alkenes

A protocol for photoinduced cross-coupling of aryl iodides having polar p-functional groups or elongated p-conjugation with alkenes has been developed. The radical cascade mechanism involving generation of aryl radicals via C-I bond homolysis of photoexcited aryl iodides and their subsequent addition to alkenes is proposed. The method enables iodide-selective cross-coupling over other halogen leaving groups with functional group compatibility on both arene and alkene motifs.
