The reactivity of substituted phencyclones in the diene synthesis reaction with N-arylmaleimides and maleic anhydride was investigated.These reactions are of the "diene-donor, dienophile-acceptor" type.The selectivity of the reactions of the cyclones with imides is determined by the electronic character of the substituents in the dienophile. "Normal" selectivity is observed in the investigated reactions, and this is consistent with the idea that the reactivity in the given series is controlled not only by orbital donor-acceptor interactions but also by localization energies.
