| 摘 要： | 采用甲苯和四氢呋喃的混合溶剂进行格氏反应，将格氏试剂与硼酸三甲酯反应后的产物结晶析出，直接过滤分出溶剂，滤出固体经碳酸钠水解即得四苯硼钠，而滤出的溶剂则可以不用干燥处理继续用作格氏反应的溶剂。

| Abstract: | Sodium tetraphenylborate was prepared from PhMgCl and trimethyl borate by making use of a solvent pair including te-trahydrofuran and toluene. After reaction the solvent was filtered off and could be used for next Grignard reaction. The solid was hydrolyzed with sodium carbonate solution to give sodium tetraphenylborate. |
