2-디브로모-9-페난트롤린 화학적 특성, 용도, 생산

• Synthesis

  Under an argon atmosphere, 2.0 mL of phosphorus tribromide was added to 2,9-dichloro-1,10-phenanthroline (70.0 mg, 0.281 mmol), and the mixture was stirred at 165°C for seven hours. The reaction solution was cooled with ice, and the aqueous solution of sodium hydrogen carbonate was added thereto little by little until the reaction solution became weakly basic. The resulting mixture was filtrated, and the filtrated matter was washed lightly with methanol. The filtrated matter was extracted with chloroform potassium carbonate aqueous solution, and the organic phase was dried over anhydrous sodium sulfate, filtrated, and concentrated on providing 76.6 mg (81.1percent yield) of the colourless solid 2, 9-dibromo-1,10-phenanthroline.
