Literature References

This salt, or the more water-soluble chloride (next entry), has been used to extract heavy metals from aqueous solution as ion-association complexes: J. Organomet. Chem., 160, 17 (1978), Z. Naturforsch. B, 33B(5), 533 (1978); Microchem. J., 22, 275 (1977). Thermally stable phase-transfer catalyst (see Appendix 2): in combination with o-phthaloyl chloride (nitrite trap), facilitates the otherwise difficult displacement by F- of a nitro-group meta to an activating group: Chem. Lett., 2213 (1989): For a similar reaction, see 4-Chlorobenzaldehyde, A12757.

Applications

Tetraphenylphosphonium bromide is a supporting electrolyte for the electroreduction of buckminsterfullerene. It is used to extract heavy metals from aqueous solution as ion-association complexes
