Application of 10351-75-4,Some common heterocyclic compound, 10351-75-4, name is 1H-Benzo[d]imidazole-5,6-dicarboxylic acid, molecular formula is C9H6N2O4, 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 Cd(NO3)2ยท4H2O (0.0308 g, 0.1 mmol), H3BIDC (0.0412 g, 0.2 mmol) and phen (0.0396 g, 0.2 mmol) with a molar ratio of 1:2:2 were dissolved in the distilled water (5 mL), and stired for 25 min, then set in a Teflon-lined autoclave and heating at 160 C for five days. After cooling to the room temperature, yellow block crystals were obtained. Yield: 28.84 mg (77%, on Cd(II) cations). The products were washed by distilled water and dried in air. Elemental analysis (%): Calc. for 1: C, 52.87; H, 3.74; N, 11.21. Found: C, 52.60; H, 3.38; N, 11.01. IR (KBr pellet, (cm-1)): 3428 (s), 3056 (m), 1717 (w), 1576 (s), 1505 (w), 1472 (w),1384 (m), 1353 (s), 1102 (m), 845 (s), 772 (m). 1H NMR (400 MHz, DMSO-d6): delta=8.97 (d, 2H, phen-H2,9), 8.81 (d, 2H, phen-H4,7), 8.40 (s, 1H, -N=CH-NH), 8.22 (d, 2H, H3BIDC aromatic H), 7.98 (d, 2H, phen-H5,6), 7.96 (d, 2H, phen-H3,8) (ppm).
The synthetic route of 10351-75-4 has been constantly updated, and we look forward to future research findings.
