In the 9,10‐anthracenedicarbonitrile‐sensitized irradiation of the title compounds 1a–f in benzene, the photocyclization of 1b–d leads efficiently to products 2b–d with five‐, six‐, and seven‐membered rings, respectively (A = 9,10‐anthracenedicarbonitrile). This cyclization is also possible with 3‐substituted derivatives of 1c . The reaction proceeds via an exciplex of the sensitizer A and alkene 1 .
