REACTION OF 2-HYDROXYETHYLHYDRAZINE WITH ACRYLONITRILE AND THE TAUTOMERISM OF THE REACTION PRODUCTS

The reaction of hydroxyethylhydrazine with acrylonitrile gave a liquid linear products (β-hydroxyethyl-β-cyanoethylhydrazine), from which crystals of 3-amino-1-hydroxyethyl-2-pyrazoline were isolated.Earlier, in brief communication the last compound was wrongly assigned the iminopyrazolidine structure.The structure of 3-amino-1-hydroxyethyl-2-pyrazoline was proved by analysis of the 1H and 13C NMR spectra.The IR spectra of the aminopyrazoline, recorded in Vaseline oil and in chloroform solution, and also study of the structure of the products from its condensationwith aldehydes make it possible to consider that the aminopyrazoline changes partly into the iminopyrazolidine form when dissolved, i.e., an uneven tautomeric equilibrium occurs.The structure of the β-hydroxyethyl-β-cyanoethylhydrazone compound was confirmed by the structure of the products from its reaction with carbonyl compounds.
