Allyl-transfer Reaction from Photoexcited Hypervalent Allylsilicon Reagent toward Dicyanobenzenes

Photoreaction between dicyanobenzenes and a hypervalent allylsilicon reagent using 2,3-dihydroxynaphthalene as a ligand on silicon efficiently proceeded to afford allyl-substituted benzonitriles in moderate to good yields. The present photoreaction was found to occur based on the excitation of the hypervalent allylsilicon reagent.
