Potassium Carbonate → 2,2'-Oxybis(6-phenylpyridine)

Participants

Reaction Conditions

Reaction Steps

A mixture of 2-hydroxy-6-phenylpyridine (1.0 g, 5.8 mmol), 2-bromo-6-phenylpyridine (1.4 g, 5.8 mmol) and potassium carbonate (807 mg, 5.8 mmol) was stirred at 200° C. for 8 hours. After the reaction mixture was cooled, to which was then added an aqueous 1 mol/L sodium hydroxide solution, the mixture was extracted with dichloromethane, the solvent was distilled off, and the residue was purified by silica gel column chromatography, thereby obtaining 1.3 g of 2,2′-oxybis(6-phenylpyridine) as colorless crystal.
