Description

Application

Triphenylphosphine oxide can be used:

• As a catalyst in Appel-type chlorination reaction of acyclic primary and secondary alcohols.[1]
• As a catalyst in stereoselective poly and dibromination of α,β-unsaturated esters and β,γ-unsaturated α-ketoester compounds.[2]
• As a promotor in the diastereoselective synthesis of α-ribofuranosides through ribofuranosylation of alcohols with ribofuranosyl iodides.[3]
