On Triazoles. VI. The acylation of 5‐amino‐1,2,4‐triazoles

Journal of Heterocyclic Chemistry, 1987
AbstractThe isomeric and tautomeric structure of I and II type monoacylated 5‐amino‐1,2,4‐triazole derivatives was studied with the help of their ir, uv, pmr and cmr spectra as well as model compounds prepared for this purpose. It was stated that the structure of the I type ring‐acylated derivatives is 2o and those of their II type isomers is 5a.

Synthesis and Characterization of Azido-Functionalized 1,2,3-Triazole and Fused 1,2,3-Triazole

The Journal of Organic Chemistry, 2023
Here, we report the nitration of NH on the 1,2,3-triazole ring and the synthesis of several nitrogen-rich energetic compounds based on key intermediate 4-azido-5-(chlorodinitromethyl)-2-nitro-2H-1,2,3-triazole (5). Starting from 4-amino-1H-1,2,3-triazole-5-carbonitrile (1), we successfully constructed compound 5 through four steps.

Mesoionic 1,2,3-Triazoles and 1,2,3-Triazole Carbenes

2014
Routine access to 1,2,3-triazoles through the copper-catalyzed azide-alkyne “click” cycloaddition reaction has promoted the rapid development of 1,2,3-triazolylidenes as ligands for transition metals. The organometallic complexes containing this kind of N-heterocyclic carbene ligands (NHCs) have shown to possess unique structural characteristics ...
