Abstract
The spatial structure of various derivatives of α,α-diamino-β-cyano-β-nitroethylene has been investigated using1H and13C NMR spectroscopy. It was shown that the configuration of the investigated push—pull enamines is determined by the possibility of creating an intramolecular hydrogen bond between NH and NO2 groups or by steric interactions. A series of 3,5-diamino-5-nitropyrazole derivatives has been synthesized by reacting these amines with hydrazine hydrate.
