Researches on substituted arylamides of dithiocarboxylic acids

IX. Cyclizing N-arylcyanoacetamides to pyrazole derivatives

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Reaction of N-aryl cyanoacetamides with hydrazine hydrate, or its monoaryl-substitution products, gives 3-arylamino-5-aminopyrazoles and 1-aryl-3-arylamino-5-aminopyrazoles. Treatment of aminopyrazoles with aryldiazonium chlorides leads to isolation of the arylazo derivatives. A hypothesis that the pyrazole derivatives synthesized have an amine structure is put forward on the basis of their chemical properties and IR spectra.
