Amines addition to α-nitrohydrazones: application to amidrazones and triazoles formation
摘要:
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. (C) 2002 Elsevier Science Ltd. All rights reserved.
