Triphenylphosphine oxide (often abbreviated TPPO) is the organophosphorus compound with the formula OP(C 6 H 5) 3, also written as Ph 3 PO or PPh 3 O (Ph = C 6 H 5). It is one of the more common phosphine oxides. This colourless crystalline compound is a common but potentially useful waste product in reactions involving triphenylphosphine.
Triphenylphosphine (IUPAC name: triphenylphosphane) is a common organophosphorus compound with the formula P(C 6 H 5) 3 and often abbreviated to P Ph 3 or Ph 3 P. It is versatile compound that is widely used as a reagent in organic synthesis and as a ligand for transition metal complexes, including ones that serve as catalysts in organometallic ...

Tributylphosphine reacts with oxygen to give the corresponding phosphine oxide (here tributylphosphine oxide): 2 P(CH 2 CH 2 CH 2 CH 3) 3 + O 2 → 2 O=P(CH 2 CH 2 CH 2 CH 3) 3. Because this reaction is so fast, the compound is usually handled under an inert atmosphere. The phosphine is also easily alkylated.
The hydrolysis of phosphorus(V) dihalides also affords the oxide: [9] R 3 PCl 2 + H 2 O → R 3 PO + 2 HCl. A special nonoxidative route is applicable secondary phosphine oxides, which arise by the hydrolysis of the chlorophosphine. An example is the hydrolysis of chlorodiphenylphosphine to give diphenylphosphine oxide: Ph 2 PCl + H 2 O → Ph ...
Triphenyl phosphate has been detected in the environment. [9] Other triaryl phosphates have been known to enter aquatic environments through volatilization and leaching from plastics, through hydraulic fluid leakages, and, to a lesser degree, through manufacturing processes. [5]
