Description

General description

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

Application

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

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.
