A useful alternative to Triphenyl­phosphine, L02502 in many applications. Advantages include its greater reactivity and the water-solubility of the by-product phosphine oxide, simplifying its removal.

In combination with phenyl isocyanate and a Pd catalyst, converts cinnamyl alcohol directly to a phosphorane, which reacts with aldehydes to give conjugated dienes: Chem. Lett., 1449 (1988):
