Application of 1455-77-2,Some common heterocyclic compound, 1455-77-2, name is 3,5-Diamino-1,2,4-triazole, molecular formula is C2H5N5, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A mixture of Hdatrz (9.9mg, 0.1mmol), NO2-H2ip (21.1mg, 0.1mmol) and Co(NO3)2¡¤6H2O (14.5mg, 0.05mmol) was dissolved in doubly distilled water (15.0mL), and the initial pH of the reactant mixture was adjusted to ca. 6 by slow addition of triethylamine with constant stirring. The resulting mixture was then transferred into a Teflon-lined stainless steel vessel (23.0mL) and heated at 140¡ãC for 72h under autogenous pressure. After the mixture was cooled to room temperature at a rate of 3.2¡ãCh?1, pink block-shaped crystals suitable for X-ray analysis were obtained directly, washed with water and dried in air (Yield: 50percent, based on CoII salt). Anal. Calc. for C20H18Co2N12O14: C, 31.27; H, 2.36; N, 21.88. Found: C, 31.25; H, 2.37; N, 21.86percent. IR (KBr pellet, cm?1): 3422 (br), 3336 (w), 3270 (w), 3083 (w), 1620 (s), 1571 (s), 1533 (s), 1366 (s), 1348 (s), 1200 (w), 1102 (w), 1068 (w), 822 (w), 785 (w), 753 (w), 735 (m), 718 (s), 669 (w), 563 (w), 525 (w), 477 (w), 433 (w).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,5-Diamino-1,2,4-triazole, its application will become more common.
