Description

General description

Sodium tetraphenylborate (Ph₄BNa) undergoes rhodium-catalyzed addition reactions with N-phenylsulfonyl aldimines to afford R(Ph)CHNHSO₂Ph.

Application

Sodium tetraphenylborate (Ph₄BNa) may be used in the synthesis of polyfunctional biaryls via modified Suzuki cross-coupling reaction. It may be employed as a derivatization reagent for the analysis of methylmercury and ethylmercury by gas chromatography (GC) coupled with atomic fluorescence spectrometry (AFS), microwave-induced plasma atomic emission spectrometry (AES) and mass spectrometry (MS).[1]

Other Notes

Reagent for the precipitation and titration of potassium[2]; For the amperometric titration of amines, quaternary ammonium compounds and potassium[3]; For the titration of quaternary ammonium surfactants; Titrant for amines and NH₄Cl in the presence of a K selective electrode

An automatic ultraviolet absorptiometric method has been developed for the determination of potassium. The method involves precipitation of potassium by addition of a known excess of sodium tetraphenylborate, removal of the potassium tetraphenylborate precipitate by filtration, and measurement of the
