DESCRIPTION
Application
Generates stable, crystalline N-acylammonium salts by ion exchange.[1] Couples with vinyl and aryl triflates to form arylalkenes and biaryls.[2]
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.[3]
