Description and Uses
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.
