Applications

Triphenylphosphine oxide is used as a catalyst, Lewis base, ligand for metals and starting material for the preparation of other phosphorus compounds. It is also used in epoxidations, Michael reactions and coupling reactions. It reacts with copper(II) halides and form coordination complexes of Copper(II). Further, it acts as a crystallization aid for chemical compounds. In addition to this, it is used for processing, extraction, separation and spectrophotometric determination of cadmium and mercury.

Notes

Incompatible with strong oxidizing agents.

Literature References

The reagent prepared from a 2:1 molar ratio of the phosphine oxide and triflic anhydride is a useful dehydrating agent, e.g. for preparation of nitriles from amides or oximes, or of amides from acids and amines: J. Org. Chem., 52, 4137 (1987). In combination with triethylamine, the reagent also dehydrates activated ketones to alkynes: Synthesis, 217 (1989).
