Synthesis and structures of 1,2,4-triazoles derivatives
摘要:
A series of novel 1,2,4-triazole derivatives were synthesized, and their structures were characterized by IR, UV-Vis, FL, NMR, ESI-MS, and elemental analysis. In the meanwhile, the single crystal structures of 3,4-diethyl-5-(4-pyridyl)-1,2,4-triazole and 3,4-dimethyl-5-(o-hydroxyphenyl)-1,2,4-triazole were determined by X-ray diffraction.

Abstract Treatment of N‐substituted acetamides with oxalyl chloride generates imidoyl chlorides, which react readily with aryl hydrazides. Following cyclization, triazoles can easily be obtained in moderate to good yields. 5‐Methyl triazoles can be further functionalized through α‐lithiation and subsequent reaction with an electrophile.
