由单、二、三氟苯酚与BCl_3反应，合成并分离了一系列含氟三芳基硼酸酯B（OArF）_3（ArF = 2-FC_6 H_4，3-FC_6 H_4，4-FC_6 H_4，2，4-F_2C_6 H_3，3，5-F_2C_6 H_3，2，3，4-F_3C_6 H_2，2，4，6-F_3C_6 H_2，3，4，5-F_3C_6 H_2）。这些硼酸盐的刘易斯酸性已被确定的NMR光谱和理论方法，并比较其完善的硼烷对应物。
A series of fluorinated triaryl borates B(OArF)3 (ArF = 2-FC6H4, 3-FC6H4, 4-FC6H4, 2,4-F2C6H3, 3,5-F2C6H3, 2,3,4-F3C6H2, 2,4,6-F3C6H2, 3,4,5-F3C6H2) have been prepared and isolated from the reactions of the mono-, di-, or tri-fluorophenol with BCl3. The Lewis acidity of these borates has been determined by NMR spectroscopic and theoretical methods and compared to their well-established borane counterpart.
