Description

General description

NaBPh4 acts as a convenient source of phenyl groups in the catalytic process, enabling the synthesis of phenylated products.[1]

Application

Generates stable, crystalline N-acylammonium salts by ion exchange.[2] Couples with vinyl and aryl triflates to form arylalkenes and biaryls.[3]

Sodium tetraphenylborate can form hydrophobic salts with amines, ammonium ions, and large alkali metal ions such as cesium or rubidium ions. Hence it is commonly used in gravimetric analysis as a precipitating agent.[4]
