실험 절차
Subsequently, the obtained 5,5′-bis(trimethylsilylethynyl)-2,2′-bipyridyl (120 mg, 0.34 mmol) and potassium fluoride (KF: 42 mg, 0.72 mmol) were added with dist. methanol (MeOH: 12 mL). The resultant mixture was then stirred under a nitrogen atmosphere at room temperature for 11 hours to obtain a reaction mixture. After that, an organic layer in the reaction mixture was then concentrated to obtain a crude product (II). Subsequently, the obtained crude product (II) was separated and purified by silica gel column chromatography (CH2Cl2=100) to obtain 5,5′-diethynyl-2,2′-bipyridyl (59.5 mg, 85% yield (in two steps)).
