| Questions And Answer | Back Directory | [Application]
Butyltriphenylphosphine chloride is a quaternary phosphonium salt containing a monoalkyltriphenyl substituent. The phosphorus atom possesses three unpaired electrons, one lone pair of electrons, and five empty 3d orbitals, giving Ph3P+ electron-withdrawing properties. This also allows the quaternary phosphonium salt cation to bind well with F-, which is beneficial for fluorination reactions. Due to its good catalytic effect, high selectivity, high thermal stability, low toxicity, and recyclability, quaternary phosphonium salt phase transfer catalysts have been widely used in recent years. |
