摘要：
Photosubstitution of dicyanoarenes with hypervalent allylsilicon reagents in the presence of anthracene efficiently proceeded to afford the allyl-substituted product in moderate to good yields. The efficiency for the present photoreaction was much higher than that for the tetracoordinate allylsilanes, because hypervalent allylsilicon reagents possess lower oxidation potential than the tetracoordinate ones, which resulted in more efficient photoinduced electron-transfer process.
