Triphenylphosphine oxide Chemical Properties,Usage,Production

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 (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.

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 is a phosphine ligand used for coupling reactions, epoxidations, and Michael reactions

Definition

ChEBI: A phosphine oxide in which the substituents on phosphorus are three phenyl groups.
