168646-54-6, 5,6-Diamino-1,10-phenanthroline is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Under nitrogen protection,A solution of 5-bromo-1-phenylindole-2,3-dione (Intermediate a) (30.2 g, 0.1 mol) and 1,10-phenanthroline-5,6-diamine (Intermediate b ) (21.0 g, 0.1 mol) was added to 200 mL of absolute ethanol.The reaction was allowed to warm to 70-75 ¡ã C for 24 hours.Reaction is completed, cooled to room temperature after the direct suction filter,The filter cake was rinsed with absolute ethanol and the crude product was crystallized from dichloroethane / absolute ethanol to give a yellow solid,That is the intermediate c, the yield of 70percent.
168646-54-6, As the paragraph descriping shows that 168646-54-6 is playing an increasingly important role.
