Sensitive Energetics from the N-Amination of 4-Nitro-1,2,3-Triazole

Energetic N-amino-C-nitro compounds 1-amino-4-nitro-1,2,3-triazole and 2-amino-4-nitro-1,2,3-triazole are characterized for the first time as energetic materials. These compounds were characterized chemically by nuclear magnetic resonance (NMR), Infrared

Synthetic approaches to 3,3'-biindolyl and 3,3'-biindazolyl derivatives

In this paper new syntheses of 3,3'-biindolyl and 3,3'-biindazolyl derivatives are described. Formation of 3,3'-biindolyl derivatives by oxidative coupling of N-acetylindole with TeCl4 gave a good yield, while attempt to use the same reaction conditions for synthesis of 3,3'-biindazolyl derivatives failed. However, conversion of 3-haloindazole derivatives to its trimethylstannane derivative, followed by palladium-catalyzed Stille cross-coupling reaction, resulted in formation of 3,3'-biindazolyl derivatives.

Deproto-metallation and computed CH acidity of 2-aryl-1,2,3-triazoles

2-Aryl-1,2,3-triazoles were synthesized by cyclization of the corresponding glyoxal arylosazones, generated from commercial arylhydrazines. The deproto-metallation of 2-phenyl-1,2,3-triazole was attempted using different 2,2,6,6-tetramethylpiperidino-based mixed lithium-metal (Zn, Cd, Cu, Co, Fe) combinations, giving results in the case of Zn, Cd, and Cu. The lithium-zinc combination was next selected to apply the deprotonation-iodination sequence to all the 2-aryl-1,2,3-triazoles synthesized. The results were analyzed with the help of the CH acidities of the substrates, determined in THF solution using the DFT B3LYP method.
