Abstract Highly polarized enediamines of the a, α-diamino-β-cyano-β-nitroethylene type have been obtained by the hydrolysis of 4-chloro-5-nitropyrimidines. Several chemical conversions of the enamines obtained have been studied, particularly leading to derivatives of 2-(cyanonitromethylene) imidazoline and-hexahydropyrimidine, and also to derivatives of N, N′-bisvinylpiperazine and 7 methylene-1, 4-diazabicyclo (2.2. 1] heptane.
