Anwendungen

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.

Bemerkungen

It is hygroscopic. Incompatible with oxidizing agents.

Reagent for Bi and Co.

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 140-150o 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-Dimethyl­glycine, A19670: Angew. Chem. Int. Ed., 37, 481 (1998).
