我給你這一段文字，你從上下文，分析一下，因?yàn)槟愕姆g我還是不太理解。謝謝 Preparation of 1-(N2)2: Method 2. A 50 mL round-bottomed flask was charged with 0.102 g (0.15 mmol) of 1-Br2 and approximately 30 mL of diethyl ether. The resulting blue suspension was cooled to -35 °C in the drybox freezer. Via microsyringe, 0.293 mL (0.293 mmol) of a 1.0 M solution of NaBEt3H in toluene was added to the reaction flask. After being stirred under a N2 atmosphere at ambient temperature for 3 h, the green-purple solution was filtered through Celite, and the volatiles were removed from the filtrate in vacuo. Recrystallization of the resulting residue from pentane at -35 °C afforded analytically and spectroscopically pure 1-(N2)2. |
