Related Products of 3112-31-0, A common heterocyclic compound, 3112-31-0, name is 1H-Pyrazole-3,5-dicarboxylic acid, molecular formula is C5H4N2O4, its 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.
In a typical synthesis, 0.17mmol (0.0300g) of H3dpc, 0.36mmol (0.0586g) of MnCl2 2H2O, 0.26mmol (0.0403g) of 4,4?-bpy and 10mL of distilled water were mixed. The reaction mixture was stirred until a homogeneous gel was formed (pH 4), sealed in a PTFE-lined stainless steel autoclave with an internal volume of 40mL and heated at 150¡ãC for 3days under autogenous pressure. After cooling to room temperature, the resulting block single crystal particles that was confirmed to be compound 3 by XRD were filtered off, washed with distilled water (3*50mL), and dried in an ambient condition. Yield 0.031g, 73percent based on H3dpc. The mother liquor was allowed to stand still for evaporation. After one week, small amount single crystals were found grown up on the wall of beaker. These crystal particles were collected and air dried at room temperature, single crystal X-ray diffraction data revealed that these particles were phase 1. Yield 0.010g, 9.4percent based on H3dpc.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
