Amines addition to α-nitrohydrazones: application to amidrazones and triazoles formation
Primary nitro compounds can be easily converted into amidrazone by addition of amines. The best yields for primary amines are obtained with a large excess of amine as oxidation products are formed. These additions were applied to the selective formation of triazole (Buzykin reaction) and pyrrole. Gr...

Summary: | Primary nitro compounds can be easily converted into amidrazone by addition of amines. The best yields for primary amines are obtained with a large excess of amine as oxidation products are formed. These additions were applied to the selective formation of triazole (Buzykin reaction) and pyrrole.
