New discoveries in chemical research and development in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 1455-77-2, name is 3,5-Diamino-1,2,4-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Computed Properties of C2H5N5
General procedure: An equimolar solution of 3,5-diamino-1,2,4-triazole (0.99 g, 0.01 mol) and 2-hydroxynaphthaldehyde (1.72 g, 0.01 mol) in dry methanol (50 mL) was refluxed for 3 h, a precipitated product was formed during refluxing. It was then cooled to room temperature, filtered, washed with methanol (35 mL), then with diethyl ether (2 × 5 mL) and dried under vacuum. Recrystallization in a mixture of methanol:dioxane (1:4) gave TLC pure product (L1) in 83percent yield. The same method was applied for the preparation of all other ligands (L2)?(L5).
