Popis: The geometries, conformations, and electron structures of the methyl esters of dimethylamino- and (1-aziridino)propiolic acid were studied by means of the MNDO method. It was shown that the energies of the lowest vacant molecular orbital may serve as a measure of the electrophilicities of these compounds. The increased electrophilicity of the ynaziridino ester is associated with the greater pyramidal character of the nitrogen atom in the aziridine ring.
