Azacyclo-octatetraenes are formed photochemically from addition of acrylonitrile or benzonitrile to p-methoxybenzonitrile: from the former system ortho-cycloadducts are also produced but irradiation of allyl cyanide or cis-cyclo-octene with p-methoxybenzonitrile yields para- and meta-cycloadducts respectively.

The photoreactions of 2-,3-, and 4-cyanoanisole with cis cyclo-octene, ethyl vinylether and acrylonitrile have been investigated. Additions of the cyclo-alkene reflect control of the reaction by the methoxy group to give predominantly meta cycloadducts by 2,6-attack. In contrast these arenes and ethyl vinylether undergo ortho cycloaddition which in the case of the product from the 2-arene isomer
