Chemical compound
Phosphonium iodide is a chemical compound with the formula PH 4I. It is an example of a salt containing an unsubstituted phosphonium cation (PH+ 4). Phosphonium iodide is commonly used as storage for phosphine[2] and as a reagent for substituting phosphorus into organic molecules.[3]
