Tetraphenylborate is an organoboron anion consisting of a central boron atom with four phenyl groups. It is a colorless anion that forms water-insoluble salts with a variety of cations. It was considered as a precipitant for caesium-137 ions in the context of radiowaste cleanup. [1]

Salts of tetraphenylborate have been used as uncouplers of oxidative phosphorylation. [2]

Oxidation of tetraphenylborate gives biphenyl and (C6H5)2BOH. [3]
