Ethenyldiphenylphosphine Oxide was used a starting material in the synthesis of sorbents for the selective and effective sorption of Am(III) from HNO3 solutions containing high concentration of Fe(III) and Zr(IV).

Diphenyl(vinyl)phosphine Oxide is a Horner-Wittig reagent for the preparation of allylic amines; it undergoes a variety of cycloaddition and conjugate addition reactions.

Diphenyl(vinyl)phosphine Oxide can be prepared (eq 1) by four methods: (a) dehydrohalogenation of a haloethyldiphenylphosphine oxide, (b) reaction of diphenylphosphinic chloride and vinylmagnesium bromide, (c) palladium-catalyzed coupling of vinyl bromide and diphenylphosphine oxide, (d) oxidation of commercially available diphenyl(vinyl)phosphine.

The reagent's toxicological properties are unknown; however, by analogy with other Michael acceptors, it should be assumed to be toxic. While radical polymerization is sluggish, diphenyl(vinyl)phosphine oxide readily undergoes anionic polymerization in the presence of Grignard reagents.
