不溶于水，易溶于苯等有机溶剂。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.
