Multiple C–B Bond Cleavage Reactions at [BAr<sup>F</sup><sub>4</sub>]<sup>−</sup> Anions Mediated by Terphenyl Phosphine Gold Catalysts
Fluorinated borates have been widely used as innocent and weakly coordinating counteranions. Among those, [BArF4]− ([B(C6H3-3,5-(CF3)2)4]−) occupies a prominent position due to the robustness of its B–C carbon bonds. Herein, we investigate C–B bond cleavage in the [BArF4]− anion mediated by cationic gold fragments of type [Au(PMe2Ar′)]+, where Ar′ stands for bulky terphenyl (C6H3-2,6-Ar2) substituents. In addition, we have exploited the stoichiometric B–C bond cleavage to construct a catalytic cycle for the synthesis of boranes under acidic conditions.
