A safe, convenient preparation of the reagent sodium tetrakis[(3,5-trifluoromethyl)phenyl]borate (NaBArF(24)) has been devised by utilizing a magnesium-bromine exchange reaction in the absence of metallic magnesium. Purified material was then rigorously dried over P(2)O(5) (NaBArF(24) with < 500 ppm H(2)O by mass) or recrystallized as a hydrate (NaBArF(24).2.6 +/- 0.1H(2)O). Accurate analysis of the water content of these samples by (1)H NMR was accomplished by using dimethylzirconocene [Cp(2)Zr(CH(3))(2)].

四基 [(3,5-三氟甲基) 苯基] 硼酸钠 (NaBArF(24))：安全制备、标准化纯化和水合分析。

通过在没有金属镁的情况下利用镁-溴交换反应设计了一种安全、方便的试剂四 [(3,5-三氟甲基) 苯基] 硼酸钠 (NaBArF(24)) 的制备方法。然后将纯化的材料在 P(2)O(5)（NaBArF(24) 和 < 500 ppm H(2)O 按质量计）上严格干燥或重结晶为水合物 (NaBArF(24).2.6 +/- 0.1H( 2)O)。通过使用二甲基锆 [Cp(2)Zr(CH(3))(2)] 完成 (1) H NMR 对这些样品的水含量的准确分析。
