Optimization of the synthesis of 2-phenyl-1,2,3-triazole

The synthesis of 2-phenyl-1,2,3-triazole by the cyclization of glyoxal phenylosazone in high-boiling solvents in the presence of copper triflate catalyst has been optimized. The structure of the product was confirmed by data of IR, 1H, 13C, and 15N NMR spectroscopy, mass spectrometry, and elemental analysis.

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

Molybdenum-Catalyzed Deoxygenation of Heteroaromatic N-Oxides and Hydroxides using Pinacol as Reducing Agent

A molybdenum-catalyzed deoxygenation of pyridine N-oxides and N-hydroxybenzotriazoles, as well as other azole N-oxides, has been developed using pinacol as an environmentally friendly oxo-acceptor. The only by-products are acetone and water making the process a convenient alternative to established protocols in terms of waste generation. The reaction is highly chemoselective and a variety of functional groups are tolerated. The processes are usually very clean allowing the isolation of the pure deoxygenated products after a simple extraction in most cases. (Figure presented.).
