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.
