- A facile and solvent-free synthesis of 3,5 -disubstituted-4-amino-1,2,4-triazoles by reactions of aromatic nitriles with hydrazine
-
A variety of 3, 5-disubstituted-4-amino-1,2,4-triazoles were prepared by reactions of aromatic nitriles with hydrazine monohydrate. The structure of 3,5-diphenyl-4-amino-1,2,4-triazole was established by an X-ray analysis.

- SYNTHESIS OF 5-SUBSTITUTED CYANOFURANS AND THEIR REACTION WITH HYDRAZINE
-
Based on the Schmidt reaction, a new method has been developed for the preparation of nitriles in furan series from the corresponding furfural derivatives.Depending on conditions, the reaction of 5-substituted cyanofurans with hydrazine leads to amidrazones, N-aminotriazoles, or 1,2,4,5-dihydrotetrazines.
