Diphenylphosphine oxide 4559-70-0

Phenylphosphine oxide is an important organic synthesis intermediate widely used in the synthesis of various pesticides and chiral phosphine ligands. It can also serve as a coupling agent in the synthesis of heterocyclic compounds, replacing alkali metal cyanides; for example, it is used in the synthesis of the herbicide paraquat under mild conditions.
