Ethyl benzoylacetimidates react with 1,2-ethanediamine or 1,3-propanediamine in absolute ethanol to afford the 2-(benzoylmethylene)-imidazolidines or -hexahydropyrimidines, respectively. The structure of these products as ketene aminals is confirmed by spectral data. Electrophilic additions of hydrochloric acid and diethyl diazenedicarboxylate to the ketene aminals are also described.
