Nonactivated arylalkenes are effectively converted to tertiary benzylic nitriles in the presence of triflic acid and trimethylsilyl cyanide. The hydrocyanation reactions result in good to excellent yield when electron-donating groups are substituted

The regio- and stereo-selectivities in the [2 + 2] photocycloaddition of a series of 1-benzoylindoles with vinyl acetate and methyl acrylate have been investigated. With some exceptions, the 1 -benzoylindoles gave exclusively or predominantly the cor
