Descrizione

Descrizione generale

Triphenyl phosphite (TPP) is an organophosphorus compound that serves as a versatile reagent in the synthesis of phosphorus ligands.

Applicazioni

Triphenyl phosphite can be used:

• As a source of phosphorus and as a ligand for the synthesis of transition metal phosphide nanoparticles via heating-up process.
• To convert alcohols to alkyl halides.
• As a peptide coupling agent.
• As a low-temperature source of singlet oxygen after forming an adduct with ozone.
• To synthesize bromotriphenoxyphosphonium bromide, a brominating agent, by reacting with bromine.
