Beschreibung

Allgemeine Beschreibung

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

Anwendung

Erzeugt durch Ionenaustausch stabile, kristalline N-Acylammoniumsalze. Koppelt an Vinyl- und Aryltriflate unter Bildung von Arylalkenen und Biarylen.

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.
