Tetraphenylphosphonium chloride is used to generate lipophilic salts from inorganic and organometallic anions. Thus, Ph4P+ is useful as a phase-transfer catalyst, again because it allows inorganic anions to dissolve in organic solvents.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

- High-temperature phase-transfer catalyst (see Appendix 2). In combination with Bis(acetonitrile) dichloropalladium(II) , 10002, provides an effective catalyst for the Heck reaction of normally unreactive aryl halides, e.g. chlorobenzene with styrene to give stilbene. The reaction is performed at 140-150° in DMF or NMP in the presence of sodium acetate. The reaction may be further improved by the addition of 10-12 mol% N,N-Dimethyl glycine, A19670: Angew. Chem. Int. Ed., 37, 481 (1998).
