Safe Preparation and Purification of Sodium Tetrakis[(3,5-trifluoromethyl)phenyl]borate (NaBArF24): Reliable and SensitiveAnalysis of Water in Solutions of Fluorinated Tetraarylborates
A safe, convenient preparation of the reagent sodium tetrakis[(3,5-trifluoromethyl)phenyl]borate (NaBArF{sub 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{sub 2}O{sub 5} (NaBArF{sub 24} with <500 ppm H{sub 2}O by mass) or recrystallized as a hydrate (NaBArF{sub 24} x(2.6 {+-} 0.1)H{sub 2}O). Accurate analysis of the water content of these samples by {sup 1}H NMR was accomplished by using dimethylzirconocene (Cp{sub 2}Zr(CH{sub 3}){sub 2}).
