What is Triisopropyl phosphite?
Chemical properties
Colorless liquid; characteristic odor. Miscible with most common organic solvents; insoluble in water; hydrolyzes slowly in water; exposure to air should be minimum; high thermal stability. Combustible.
The Uses of Triisopropyl phosphite
Triisopropyl phosphite can be used as a reactant:
- With Ru-based indenylidene complexes to form 1st generation complexes for metathesis reactions.
- In Perkow-type reaction to synthesize compounds containing polarized carbon-carbon double bonds.
- For the synthesis of phosphonohydrazines by reacting with arylamines and isoamyl nitrite.
It can also be used as an alternative to triphenylphosphine in Mitsunobu reaction to facilitate the isolation of products.
The Uses of Triisopropyl phosphite
Intermediate for insecticides, component of vinyl stabilizers, lubricant additive, specialty solvent.
Purification Methods
Distil it from sodium, under vacuum, through a column packed with glass helices. (This removes any dialkyl phosphonate.)
