Abstract
|
In energetic materials research, much effort has been devoted to the development of environmentally benign, “green” energetic materials. Tetrazoles are readily accessible nitrogen-rich energetic compounds. Herein, we would like to report a novel, facile, eco-friendly and one-pot process for synthesis of 5-substituted 1H-tetrazoles via a domino Knoevenagel condensation and 1, 3 dipolar cycloaddition reactions. This general protocol provides 5-substituted 1H-tetrazoles in good yields under mild reaction conditions. These tetrazoles were characterized by FT-IR and 1H-NMR, 13C-NMR spectroscopy and thermogravimetric analysis.
