Some common heterocyclic compound, 162848-16-0, name is 4-[1,2,4]Triazol-1-yl-benzoic acid, molecular formula is C9H7N3O2, 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. category: Triazoles
General procedure: The ligand 4-Htba (0.1 mmol) was dissolved in DMF (5 mL), to which a DMF solution (5 mL) of Cd(NO3)2¡¤4H2O (0.1 mmol) was added with stirring for ca. 30 min. Then, the solution was sealed in a Teflon-linear autoclave and heated at 100 C for 3 days, after cooling to room temperature at a rate of 10 C/h, colorless blockc rystals of complex 1 were obtained in 58% yield (20.0 mg). Anal. Calcd for C10H7CdN3O4: C, 34.75; H, 2.04; N, 12.16%. Found: C, 34.71; H, 2.06; N, 12.14%. IR (KBr, cm-1): 1606vs, 1575vs, 1542vs, 1449m, 1410vs, 1368s, 1337s, 1303s, 1281s, 1229m, 1149m, 1051m, 994w, 975m, 873w, 854m, 812w, 781m, 724w, 698w, 669w, 646w, 541w. The same synthetic procedure as that for 1 was used except that Cd(NO3)2¡¤4H2O was replaced by Pb(NO3)2 (0.1 mmol), forming colorless block crystals of 2 in 54% yield (23.8 mg). Anal. Calcd for C10H7PbN3O4: C, 27.27; H, 1.60; N, 9.54%. Found: C, 27.22; H, 1.64; N, 9.49%. IR (KBr, cm-1): 1603s, 1557vs, 1383vs, 1340s, 1305m, 1277m, 1222m, 1143w, 1050w, 964w, 848w, 782m, 719w, 696w, 666w, 641w, 541w.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 162848-16-0, its application will become more common.
