Abstract

Copper–zinc supported on Al2O3–TiO2 was found as a simple and efficient heterogeneous catalyst for the oxidative synthesis of 1, 2, 4-triazole derivatives using air as the green oxidant under ligand-, base-and additive-free conditions. The heterogeneous reactions carried out smoothly with a large range of substrates, including NO2-, vinyl-, pyrimidine-and imidazole-contained starting materials, and provided corresponding triazoles in moderate ...
