Diisopropyl phosphite

Description:

Diisopropyl phosphite is an organophosphorus compound characterized by its phosphite functional group, where two isopropyl groups are attached to a phosphorus atom. It is typically a colorless to pale yellow liquid with a faint odor. This compound is known for its role as a reagent in organic synthesis, particularly in the preparation of phosphonates and phosphonamidates. Diisopropyl phosphite exhibits moderate toxicity and should be handled with care, as it can cause irritation to the skin, eyes, and respiratory system. It is soluble in organic solvents but has limited solubility in water. The compound is also used as a stabilizer in various chemical processes and can act as a ligand in coordination chemistry. Its reactivity is influenced by the presence of the phosphorus-oxygen bond, making it a valuable intermediate in the synthesis of more complex phosphorus-containing compounds. Proper storage conditions are essential to maintain its stability and prevent degradation.

Diisopropyl phosphite

CAS: 1809-20-7

Diisopropyl phosphite is a pyrimidine compound that is used in organic synthesis. It is an intermediate in the asymmetric synthesis of various pyridines. Diisopropyl phosphite reacts with hydrochloric acid to produce hydroxybenzoic acid and hydrogen gas. The first step in the reaction mechanism involves a palladium-catalyzed coupling reaction between diisopropyl phosphite and methyl iodide, which leads to the formation of a tetrahydrofuran ring system. Such reactions are generally carried out at low temperatures to minimize decomposition of diisopropyl phosphite. Diisopropyl phosphite has been shown to be chemically stable, but has low bioavailability due to its high reactivity with biological molecules such as proteins and lipids.
