三乙基氧鎓四氟硼酸盐制备

1. 通过3-氯-1,2-环氧丙烷与BF₃-OEt₂配合物反应制备而来。

2. 将2升三颈烧瓶、搅拌器、i商液漏斗和带有千燥管的冷凝器放入110℃的烘箱中干燥，趁热安装，在干燥氮气流中冷却。烧瓶中加入500毫升用钠干燥过的乙醚和284克(252毫升，2 .00摩尔)新蒸的三氟化硼乙醚溶液。将140克(119毫升，1.51摩尔)3一氯环氧丙烷滴加入搅拌液中，滴加速度以保持剧烈沸腾即可(约需1小时)。加完后再回流1小时，室温下放置过夜。把搅拌器换成吸滤管。吸出四氟硼酸三乙基氧渝晶体上面的清亮乙醚。这些操作都需要在氮气保护下进行，避免潮湿空气进入烧瓶。用3份500毫升钠干燥过的乙醚洗涤晶体。把烧瓶放到干燥箱中。在氮气保护下用玻芯漏斗收集产品并装瓶。四氟硼酸三乙基氧滋是无色晶体。
