In 2019,Dalton Transactions included an article by Ding, Tao; Zhang, Sheng; Zhang, Weiqiang; Zhang, Guofang; Gao, Zi-Wei. Application In Synthesis of 2,6-Dibromopyridine. The article was titled 《Highly selective C2H2 and CO2 capture and magnetic properties of a robust Co-chain based metal-organic framework》. The information in the text is summarized as follows:
A robust Co-based metal-organic framework, [Co3(L)(OH)2(H2O)4]·2DMF·2H2O (1), was synthesized under solvothermal conditions using pyridyl-decorated tetracarboxylic acid, 2,6-di(2′,5′-dicarboxylphenyl)pyridine (H4L). Structural anal. demonstrates that 1 is a 3D framework based on 1D alternate Co4 chain units. The desolvated structure of 1a contains 1D open channels with a highly polar pore surface decorated with open metal sites, μ3-OH group and pyridyl group sites, exhibiting multipoint interactions between C2H2 and CO2 mols. The framework efficiently takes up C2H2 and CO2 with significant selectivity for C2H2 and CO2 over CH4. In addition, the magnetic properties of 1 were studied and it showed a slow freezing process. In the part of experimental materials, we found many familiar compounds, such as 2,6-Dibromopyridine(cas: 626-05-1Application In Synthesis of 2,6-Dibromopyridine)
2,6-Dibromopyridine(cas: 626-05-1) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. Application In Synthesis of 2,6-Dibromopyridine
