A protocol for photoinduced cross-coupling of aryl iodides having polar π-functional groups or elongated π-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.

Dehydrogenative silylation of alkenes with silanes to produce allylsilanes is achieved through manganese catalysis with a wide scope of substrate tolerance. This transformation involves silane radicals initiated by manganese complex without additional oxidant additives. It offers a general, convenient and practical protocol with excellent functional group compatibility and gram-scale capacity for the modular synthesis of allylsilanes.

The metal- and photocatalyst-free synthesis of substituted allylarenes has been carried out under visible light driven conditions. The process was based on the photogeneration of aryl radicals from arylazo sulfones and their ensuing reaction with allyl sulfones. The developed procedure was very efficient when using substrates bearing electron-withdrawing groups, and allowed for the preparation of α-benzyl styrenes and 2-benzyl acrylates in good yields.
