HETEROCYCLIZATION OF COMPOUNDS CONTAINING DIAZO AND CYANO GROUPS. TWO PATHWAYS IN THE CYCLIZATION OF 2-DIAZO-2-CYANOACETIC ACID DERIVATIVES UNDER THE INFLUENCE OF BASES

Article abstract of DOI:10.1007/BF00522732

1,2,3-Triazol-5-olates are formed in the reaction of diazomalonodiamide and 2-diazo-2-cyanoacetic acid amide and N-methylamide with sodium ethoxide, triethylamine, and ammonia.The products of the reaction of 2-diazo-2-cyanoacetamide with primary amines are mixtures of 4-cyano-1,2,3-triazol-5-olates and 5-amino-1-alkyl-1,2,3-triazole-4-carboxamides.
