The 1,3-dipolar cycloaddition reactions of aryl azides with pyrrolidinocyclohexene and endo-dicyclopentadiene and also of C-benzoyl-N-phenyl nitrone with substituted norbornenes were investigated by a thermochemical method.On the basis of the obtained data a comparison was made of the localization energies of the aryl azides and nitrones.In the reactions of C-benzoyl-N-phenyl nitrone with substituted norbornenes the opposite effects of the donor-acceptor interactions and the localization effects on the reactivity lead to loss of the sensitivity of the condensations to change in the electronic character of the substituents in the dipolarophile.

The reactivity of aryl azides in 1,3-dipolar cycloaddition with substituted norbornenes was determinated.In the series of investigated compounds the activity of the addends is determined primarily by the orbital donor-acceptor interactions.Description of the reactivity of the dipolarophiles with wide variation in the structure of the cyclenes requires consideration of the localization energies in addition to the donor-acceptor characteristics.
