| | Triphenylphosphine oxide Usage And Synthesis |
| Description | Triphenylphosphine oxide (TPPO) is a coordinating solvent used to activate crystallization of chemical compounds. It has been used in flame retardant applications, as an epoxy cure catalyst, and more recently, to produce nanostructures. | | Chemical Properties | White solid | | Uses | Triphenylphosphine oxide is a phosphine ligand used for coupling reactions, epoxidations, and Michael reactions | | Uses | Triphenylphosphine oxide can be used:
As a catalyst in Appel-type chlorination reaction of acyclic primary and secondary alcohols.
As a catalyst in stereoselective poly and dibromination of α,β-unsaturated esters and β,γ-unsaturated α-ketoester compounds.
As a promotor in the diastereoselective synthesis of α-ribofuranosides through ribofuranosylation of alcohols with ribofuranosyl iodides. | | Uses | Triphenylphosphine Oxide (Orlistat USP Related Compound C) is a catalyst in the conversion of aldehydes into 1,1-dichlorides. Triphenylphosphine Oxide is used as a catalyst for the synthesis of hightly functionalized α-CF3 γ-keto esters. | | Definition | ChEBI: A phosphine oxide in which the substituents on phosphorus are three phenyl groups. | | Synthesis Reference(s) | Tetrahedron Letters, 31, p. 5463, 1990 DOI: 10.1016/S0040-4039(00)97873-0 | | Flammability and Explosibility | Not classified | | reaction suitability | reagent type: ligand
