Triphenylphosphine oxidation

Triphenylphosphine oxide (often abbreviated TPPO) is the organophosphorus compound with the formula OP(C6H5)3, also written as Ph3PO or PPh3O (Ph = C6H5). This colourless crystalline compound is a common but potentially useful waste product in reactions involving triphenylphosphine. It is a … See more Ph3PO is a tetrahedral molecule related to POCl3. The oxygen center is relatively basic. The rigidity of the backbone and the basicity of the oxygen center make this species a popular agent to crystallize otherwise difficult to … See more Ph3PO is a ligand for "hard" metal centers. A representative complex is the tetrahedral species NiCl2(OPPh3)2. Ph3PO is a common … See more Ph3PO is a byproduct of many useful reactions in organic synthesis including the Wittig, Staudinger, and Mitsunobu reactions. It is also formed when PPh3Cl2 is employed to convert See more WebApr 12, 2024 · The work is an efficient and selective additive-free oxygenation of aromatic benzylic C—H bonds using H 2 O 2 as an oxidant catalyzed by simple metalloporphyrins (T (2,6-diCl)PPFe) under non-additive and mild conditions, achieving better ethylbenzene conversion (up to 27.44%) and improved ketone selectivity (up to 85%).
