• 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.
• Uses: Triphenylphosphine oxide is a phosphine ligand used for coupling reactions, epoxidations, and Michael reactions 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. 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.
