7089-68-1, 2-Chloro-1,10-phenanthroline is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
7089-68-1, 2-(1H-Imidazol-1-yl)-1,10-phenanthroline was prepared according to the followingmethod. 2-Chloro-1,10-phenanthroline (4.29 g, 0.02 mol) and imidazole (1.63 g,0.024 mol) were dissolved with 100 mL of DMF and potassium carbonate (4.16 g, 0.030 mol) was added into the solution. After the reactants were refluxed for 72 h at110 ¡ãC, the solvent was removed by reduced pressure distillation. The pale yellow sediment appeared after 30 mL iced water was added into the remains and fully stirred.The pale yellow solid 2-(1H-imidazol-1-yl)-1,10-phenanthroline (4.5 g, yield: 91.8percent) was obtained after the sediment was washed with iced water until the pH value of the filtratewas 7.
