Abstract
New method for the study of reactivity of highly reactive compounds wa s proposed and applied to determine the effect of substituents in alph a-diazoacetamidines, and -imidates. The introduction of electron-relea sing groups to the nitrogen atom of the amidine, and imidate functions was shown to increase the reactivity of the substances studied. The r esults obtained are in good agreement with the heteroelectrocyclic mec hanism suggested for the cyclization of these compounds.
