Diphenylphosphine oxide is an important organic synthesis intermediate widely used in the synthesis of various pesticides and chiral phosphine ligands, and can replace alkali metal cyanides as coupling agents for heterocyclic compound synthesis, such as the mild synthesis of herbicide paraquat.

Diphenylphosphine oxide is commonly used in the preparation of triphenylphosphine oxide, alkyne addition, and Wittig Horner reaction reagents. The synthesis of diphenylphosphine derivatives involves the coupling of Ph2P (O) H with trifluoromethanesulfonic acid aryl ester, and the reduction of phosphine oxide to obtain diphenylarylphosphine, which is a commonly used chiral ligand.
