Highly polarized enamines. 2. Synthesis and investigation of the further amination of derivatives of α,α-diamino-β-cyano-β-nitroethylene

Article abstract of DOI:10.1007/BF01164870

Highly polarized enediamines of the α,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. 1997 Plenum Publishing Corporation.
