Sodium Tetrakis[(3,5-trifluoromethyl)phenyl]borate (NaBArF(24)): Safe Preparation, Standardized Purification, and Analysis of Hydration.


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… (More)
