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 ...
The structure of the phosphine oxide is not strongly perturbed by coordination. The geometry at phosphorus remains tetrahedral. The P-O distance elongates by ca. 2%. In triphenylphosphine oxide, the P-O distance is 1.48 Å. [3] In NiCl 2 [OP(C 6 H 5) 3] 2, the distance is 1.51 Å (see figure).
Melting point: 140 °C (284 °F; 413 K) (with decomposition) ... (III)Cl 3 with triphenylphosphine oxide results in precipitation of solid [MnCl 3 (OPPh 3) 2].
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 ...
