Irradiation of arylcyclopropanes bearing at least one electron-withdrawing group with a tertiary amine in acetonitrile resulted in the formation of the regioselective addition product of the amine along with the reduction product. ... Photochemistry of cyclopropanes has received much attention from the mechanistic and synthetic points of view.1 Direct irradiation generally results in the formation of complex product mixtures, since ring cleavage generates 1,3-biradicals which either ...
