在氮?dú)釴2保護(hù)下,首先 由鎂粉、I2和2-溴聯(lián)苯 在THF溶液中 得到 格式試劑,將 格式試劑 加入到 體系當(dāng)中 回流12小時(shí),然后 冷卻到室溫 并將 反應(yīng)液 傾倒 至500ml冷水中,于室溫下 攪拌 兩個(gè)小時(shí),氯仿萃取,有機(jī)相 旋蒸濃縮 即可得到粗品,烘干,用于 下一步反應(yīng)。 Under the protection of N2, firstly the Grignard reagent was obtained by adding magnesium powder, I2, 2-bromobiphenyl into THF solution. Then the Grignard reagent was added into the system for 12h of reflux reaction before cooling to the room temperature. After that, the reaction solution was poured into 500ml of cold water and keep stirring for 2h at room temperature. Then through chloroform extraction, as well as the rotary evaporateion and concentration of organic phase within, the crude product can be obtained, which was dried for the reaction in the next stage. |
