Aplikasi

Diphenylphosphine oxide umume digunakake kanggo nyiapake triphenylphosphine oxide, penambahan alkuna, lan reagen reaksi Wittig Horner. Sintesis turunan diphenylphosphine nyakup kopling Ph2P (O) H karo aril ester asam trifluoromethanesulfonic, lan reduksi fosfin oksida kanggo entuk diphenylarylphosphine, yaiku ligan kiral sing umum digunakake.
