General description

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

Application

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.
