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. 162848-16-0, name is 4-[1,2,4]Triazol-1-yl-benzoic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Formula: C9H7N3O2
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.
