용도

Sodium tetraphenylborate is used as a precipitating reagent for potassium and as a protecting agent to protect amino acids. It is used in the preparation of N-acylammonium salts. It finds application as a phenyl donor in palladium-catalyzed cross-coupling reactions to prepare arylalkenes and biaryl compounds. It is used in inorganic and organometallic chemistry due to its solubility in nonpolar solvents. Furthermore, it is involved in the isolation of complexes having dinitrogen ligands.

참고

Light sensitive. Incompatible with strong acids and strong oxidizing agents.
