A convenient method of synthesis of 2-(methoxycarbonylmethylene)-substituted imidazolidines and imidazolidinium bromides, and also of bicyclic diazo compounds has been developed starting from methyl bromopropiolate and ethylenediamine and its derivatives.

On the basis of the results of IR and UV spectroscopy, a considerable decrease in the efficacy of the conjugation of the unshared pair of the nitrogen atom with a carbonyl group in ynaziridines as compared with ynamines has been shown.The difference in the electronic structures of these compounds finds its reflection in their chemical behavior: the electrophilicity of the triple bond in an ynaziridine is higher than that in the analogous ynamine in reaction with amines.
