Reference 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.
Europium oxide (0.1 mmol, 35.2 mg),H3bidc (41.2 mg, 0.2 mmol) and a solution (1 ml) of oxalic acid(0.1 M) were dissolved in water (10 ml) at room temperature.After continuous stirring for 10 min, the mixture was sealed ina Teflon-lined stainless steel vessel (23 ml), heated at 180 C for 3 d under autogenous pressure and cooled slowly to room temperature. Yellow block-shaped crystals of 1 were harvestedin a yield of 80% (based on Eu). Elemental analysis (%)calculated for C10H8EuN2O8: C 27.54, H 1.85, N 6.42; found: C27.32, H 1.90, N 6.51. IR (KBr, cm-1): 3130 (m, br), 1680 (s),1620 (m), 1575 (s), 1410 (w), 1380 (m), 1209 (m), 1102 (s), 1110(vs), 1000 (m), 890 (s), 813 (m), 650 (w), 580 (w).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1H-Benzo[d]imidazole-5,6-dicarboxylic acid, its application will become more common.
